Most electric motors or motor equipment consist of drives. In addition to the good performance of linear motor, good driving performance is also different from other motors, so what drive is used for linear motor? Why is it better than other motors? Then the editors of ADTECH linear motor driver manufacturer will give you a detailed introduction, with the following contents:
Linear motor driver application system is not only a linear motor driver with good performance, but also a control system that can achieve technical and economic requirements under safe and reliable conditions. With the development of automatic control technology and microcomputer technology, there are more and more control methods for linear motor driver. The research of linear motor driver control technology can be divided into three aspects: first is the traditional control technology, the second is the modern control technology, the third is the intelligent control technology.
Traditional control techniques such as PID feedback control and decoupling control have been widely used in AC servo systems. Among them, PID control contains the past, present and future information in the dynamic control process, its configuration is almost optimal, with strong robustness, is the most basic control mode of AC servo motor drive system. In order to improve the control effect, decoupling control and vector control are often used.
The traditional control technique is simple and effective when the target model is fixed, invariant and linear, and the operating conditions and operating environment are fixed. However, in the case of high precision and high performance, the changes of object structure and parameters must be considered. Only through the influence of various nonlinearity, the change of operating environment, environmental disturbance and other time-varying uncertain factors, can the satisfactory control effect be obtained. Therefore, modern control technology has attracted great attention in the research of linear motor driver control. Common control methods include adaptive control, sliding mode variable structure control, robust control and intelligent control.
In recent years, intelligent control methods such as fuzzy logic control and neural network control have been introduced into the drive system of linear motor. At present, the existing mature control methods, such as fuzzy logic, neural network and PID control, learn from each other to obtain better control performance.
