Description

technical field [0001] The invention relates to a permanent magnet synchronous motor control system, in particular to a permanent magnet synchronous motor self-disturbance composite control system, which belongs to the technical field of high-precision servo control systems. Background technique [0002] The permanent magnet synchronous motor has the advantages of simple structure, small size, high efficiency and reliability, and good low-speed operation performance, and its application range is becoming wider and wider, especially in occasions and fields that require high motor performance and control accuracy ( Such as high speed, high precision, high reliability and high anti-interference ability) have received more and more attention. However, the permanent magnet synchronous motor is essentially a strongly coupled, multivariable, nonlinear complex system, and during the operation of the motor, the model parameters may often be time-varying, coupled with the influence of...

Problems solved by technology

Since the above three steps are independent, there are many people involved in the development process, but each person has a different understanding of the design ideas, which will lead to deviations in the work

Moreover, the testing link of the traditional development mode is at the last step, so the previous errors cannot be found in time. However, as long as there is an error in any step in the previous link, it may cause the failure of the entire system

As a result, the product development cycle is longer and the efficiency is lower

In addition, the traditional code programming is complicated, and it often requires millions or even tens of millions of lines of code to complete a large project, and a small project also requires hundreds or thousands of lines of code

Moreover, the traditional development model is not easy to find errors in time, which leads to more costs to repair
