Vector Control System

In order to achieve closed-loop control，it is generally required to know the position and speed of the motor rotor through installed photoelectric encoder, rotary transformer and some other mechanical sensors on the rotor shaft . But these sensors increase the system cost and the interface circuits between the motor and the control system, and reduce the control accuracy and reliability of the system.This article designs a sensorless vector control system for permanent magnet synchronous motor, and introduces the hardware structure and the working principle of the system, and designs control circuit and vector control software based on IRMCF341 chip. The result of test shows that the system has a steady state performance and a high control precision. The motor runs well without the position sensor and at the same time achieves a much higher level of control performance.

Exponential Reaching Law

Abstract An improved integral sliding mode observer (SMO) is proposed for the double closed-loop control system of Surface-Mounted Permanent Magnet Synchronous Motor(SPMSM) in this paper. By observing the stator current, the extended back Electromotive Force(back-EMF)of the motor is estimated, and the position and angle of the rotor are obtained by using the Phase-Locked Loop (PLL) structure. The improved integrated SMO control system not only ensures the system to converge to the equilibrium point in finite time, but also reduces the steady-state error. A new exponential reaching law is also designed in which the sgn (s) of the constant velocity term is replaced by the sigmoid (s). For improving the reaching speed, the gain adaptive function is added to the exponential term of the approaching law to make its coefficient change with the system state. Simulation results compared with the traditional SMO show that the control system based on the improved SMO can reduce observation error, enhance robustness, and suppress chattering phenomenon.

According to the characteristics of pulse-load torque of the treadmill, the key technical problems of drive control system in the treadmill with a permanent magnet synchronous motor (PMSM for short) are analyzed. The internal disturbance and external disturbance in the system are observed using the extended state observe (ESO for short) and the system is compensated using the auto-disturbance rejection controller (ADRC for short). The simulation results show that ADRC has better dynamic performance and better robustness to the load disturbance and the motor parameter variation.
