[Abstract]:In recent years, with the development of science and technology, new technology and new technology, new power electronic devices and high performance materials have been developed and put into use. With the emergence of new permanent magnet materials, the PMSM(Permanent Magnet Synchronous Motor, PMSM control strategy has been developed rapidly in various fields of application, which has become a hot topic for discussion by experts and scholars. Vector control based on magnetic field orientation is one of the most important control strategies in the field of permanent magnet synchronous motor (PMSM) because of its simple control and easy implementation. This paper focuses on vector control of permanent magnet synchronous motor (PMSM). The dynamic response speed and anti-interference ability of motor control are improved, and the steady-state error of motor control is reduced. The theory of variable Structure control (VSC) is an advanced nonlinear control theory put forward by former Soviet scholars in 1950s. The characteristic of the control is that the control model is not fixed, and the controller switches frequently among several different control modes according to the change of the system state. SMC Sliding Mode control (sliding mode control) is a new control theory developed from the control theory. The most outstanding advantage of sliding mode variable structure control is that the design of its control model is independent of the control object's own model, which is insensitive to the disturbance of system parameters and has strong robustness, so it is widely used in the field of motor control. In this paper, the vector control of permanent magnet synchronous motor (PMSM) is studied, and the sliding mode control is introduced into the traditional vector control. The sliding mode controller is designed to control the motor speed. In order to reduce the steady state error of the speed regulation, the integral sliding mode control is introduced into the controller. The permanent magnet synchronous motor (PMSM) control needs to know the precise information of rotor position and speed. The sensor is used to detect the speed and position of PMSM, which makes the structure of PMSM complex and reduces the reliability of the control system. In this paper, two kinds of rotor information detection strategies of PMSM are designed, one is model reference adaptive observer control strategy based on sliding mode control, the other is sliding mode observer control strategy. Finally, the simulation results show that the designed control strategy can effectively detect the rotor phase and speed of PMSM, and realize PMSM speed sensorless control.
