Market share: Dedicated controller > PC-Based control > PLC control
The controller has three control methods: dedicated control, PC-Based control and PLC control. Of the three types of motion controllers, the proportion of dedicated controllers used for motion control is highest. Data show that in 2019, the proportion of dedicated controllers for motion control has reached 39%, followed by PC-Based motion controllers and PLC systems, with 32% and 29%, respectively. Special controllers are developing rapidly in machine tools and high-end industrial robots, and PC-Based controllers are growing rapidly in engraving machines, semiconductors, logistics, laser processing machines and other fields. The demand for industrial robots in the automotive, electronics, pharmaceutical and other industries has directly stimulated the rapid development of motion controllers in the field of robots.
The local controller software control algorithm needs to be improved
Controllers include hardware and software two parts, domestic brands in the hardware part has been basically mastered, to the public as the representative of the brand in the software control algorithm maturity, design and other aspects of continuous improvement, is trying to narrow the gap with several international brands. It is understood that in terms of price, the unit price of imported controllers is mostly more than 10,000 yuan, domestic controller prices in the tens of thousands of yuan below.
According to statistics, due to the high requirements of industrial robots for motor skills, especially the controller reliability, safety requirements of higher standards of multi-joint robots, the basic use of imported controllers. But for SCARA robots with few shafts, small range of motion and low speed requirements, domestic motion controllers have been able to meet the requirements of daily work, so SCARA robot controllers mostly use domestic brands of motion controllers.
In addition, most of the domestic controller enterprises only produce universal controllers, focusing on the field of industrial robot controllers in the field of a small number of enterprises, there are currently popular and so on. Due to the late entry into this field, and the controller function development follows from simple to complex steps, the domestic controller brand is in the stage of continuously strengthening software development capabilities.
Domestic market competition pattern
At present, the domestic sports controller market, mainly dominated by foreign brands, international industrial automation giants have a long history of development, with strong technical research and development strength, products through the market long-term certification, has formed a good market reputation. In the case of industrial robots, foreign companies account for 80% of the market.
Local sports controller development time is late, in terms of technology and performance, and foreign investment has a certain gap. However, with good product cost-effective and use performance, in the domestic market there are signs of gradual improvement. In recent years, under the guidance of policy, increase research and development investment, and through learning, absorption, digestion of international advanced control technology, has gradually mastered the core control technology.
