Intelligent controller will become the mainstream trend of the development of industrial robot controller

is it human who commands robots to work

no, it's the controller

controller (English Name: controller) refers to the master device that controls the start, speed regulation, braking and reverse of the motor by changing the wiring of the main circuit or control circuit and changing the resistance value in the circuit according to the predetermined sequence

industrial robot controller mainly controls the motion position, posture and trajectory of the robot in the workspace, operation sequence and action time, etc

the global motion control market has developed rapidly under the wave of intelligent manufacturing. As one of the three core parts of industrial robots to comprehensively improve the technical content and product added value, the controller is the decision-making body to issue commands, and the brain of automatic chemical plants, which is designed to issue and transmit action instructions for robots

therefore, mastering the dominance of the controller is equivalent to controlling the performance of the robot. This is one of the important factors that robot leading enterprises at home and abroad pay attention to the research and development of controllers

the growth rate of the global motion control market fell in 2019

according to the latest motion control market report of interact analysis, the global motion control market fell by 3.8% in 2019 compared with last year

controller is a part of the subdivision field of PLC control, accounting for 12% of the total cost of parts. With the continuous downturn in the automation environment and the decline in the sales of industrial robots, as the core components of the upstream production of industrial robots, the market demand for controllers is inevitably affected

in 2019, the growth rate of industrial robot market slowed down, and the income fell by 4.3%. The specific adverse factors causing the decline of the industry are mainly attributed to the global economic slowdown, the trade war and the uncertainty of the global automotive industry

in addition, the market situation of machine tools, rubber and plastic machinery, pulp and paper machinery and other capital intensive machinery industries with the same huge demand for controllers in 2019 is also not optimistic. The high rebound effect of interact anal material can feed back a lot of energy. Ysis predicts that the global machinery industry will decline by about 4% or more in 2019

the localization of controller is low, but the prospect is promising

in the field of industrial robots, reducer, servo motor and control system are collectively referred to as the core parts of robots, accounting for 72% of the total cost of robots. Among them, the reducer accounts for 36%, the servo motor accounts for 24%, and the control system accounts for 12%. At present, many domestic controllers have achieved breakthroughs in technology, but their scale is still less than that of foreign giants

controller has become a common production mode of leading enterprises in the world. In China, the four families of industrial robots account for 55%, of which fanako accounts for 18%, KUKA accounts for 14%, abb robots account for 13%, and Yaskawa accounts for 10%

at the same time, the controllers of the four families account for 53% of the Chinese market, of which fanako accounts for 16%, and it is necessary to rely on plastic parts to connect them together. KUKA accounts for 14%, and ABB Robot accounts for 12%. The proportion of robot body market and controller market is basically the same. However, the domestic brand controller market accounts for less than 16%, which shows that in the field of controller in China, the degree of domestic production is relatively low

at present, in China's motion controller market, manufacturers such as German Siemens, Taiwan Xindai, Taiwan Baoyuan, Taiwan Advantech, Beijing caiente, Mitsubishi, Rockwell, Hong Kong Gugao, Omron, Schneider and so on account for half of the market share,

in addition to controllers, The market share of domestic brand reducers is less than 10%, and servo motors account for only 22%. On the whole, the localization of Chinese industrial robot parts needs to be improved

however, with the continuous improvement of the localization rate of China's industrial robots, compared with the decline in the growth rate of the global control movement market, the growth rate of the domestic controller market scale shows an opposite trend, rising against the trend. It is expected that the scale of China's motion control market will exceed 2.1 billion yuan in 2019

the development path of domestic controllers is blocked and long

at present, domestic controllers have achieved major breakthroughs, especially in the hardware requirements of controllers, they have basically reached self satisfaction. Chinese industrial robot representative enterprises such as Huichuan technology, Easton, xinshida and other listed companies have achieved independent research and development of controller and servo system technology

in the layout of industrial robot control system and servo system, the products of Aston and xinshida are mainly used for independent brand robots and export sales, while Huichuan technology is mainly exported

in the field of industrial robots, controllers and servo systems are closely related. The integration of motion control is the future application trend, but it needs to be used in combination with ontology

at present, the domestic controller market mainly has the following problems:

1. To a certain extent, the types of controllable robots of domestic controllers are complete, but there are still some gaps compared with giant enterprises in terms of operation accuracy, stability, response speed, ease of use, etc., and there is still a lot of room for progress in China

2. The binding effect between robot body and parts is strong. Generally, mature robot enterprises can achieve independent research and development and control of body and core parts to ensure stability and maintain the technical system. In China, the market share advantage of foreign ontology is significantly greater than that of domestic ontology, and the same is true of the controller market

at present, there are strong manufacturers providing controller parts such as Keba, Beifu, and baccalais in the world, and domestic enterprises that only do controllers are difficult to break through

3. The cost performance of domestic controllers is high, which is both an advantage and a disadvantage for the structure and composition of universal material testing machine. The performance of the advantage is that it can occupy the middle and low-end market and emerging fields. For example, the market demand for general-purpose robots with low requirements for robot accuracy has a broad development prospect. The disadvantage is that for the high-end market, the exploration of domestic products has a long way to go

explore the future and future of domestic controllers

under the environment of continuous downturn of capital in 2019, the market of domestic controllers is still developing against the market trend. With the increasing density of Chinese robots year by year, the localization of Chinese industrial robots continues to improve, and domestic components also usher in important development opportunities

1. As the production capacity of major domestic manufacturers continues to climb, the acceptance of domestic parts and components of industrial robots continues to improve, and the market prospect of domestic controllers is broad

2. The progress of hardware technology in foreign-funded enterprises has slowed down, and domestic enterprises have a good opportunity to catch up. At present, the hardware technology of robot parts tends to be mature, and it is difficult to have subversive innovation. The stagnant pace of foreign capital provides a good opportunity for domestic controller enterprises to catch up

domestic enterprises can combine the development experience and industrial status of giants, master the core technology of motion control, improve brand awareness, pay attention to independent research and development, improve the added value of ontology, and penetrate into high-end fields while paying attention to cost performance

3. Emerging industries such as automotive electronics and new energy are emerging fields of domestic controllers. The rapid growth of automotive electronics market and new energy vehicle market has brought huge incremental space to domestic controllers

China's new energy vehicle output continues to grow at a high speed

4. At present, the development of modular and standardized industrial robot controllers with open structure has become the mainstream trend of the development of industrial robot controllers. Artificial intelligence is an important opportunity for the development of domestic robots and domestic parts. With the strong support of national policies, Ontology manufacturers in the field of deep ploughing robot controllers are expected to break through and improve the market share of domestic controllers
