- Abstract:
- According to the decoupling analysis of various strong coupling factors in the surface-mounted permanent magnet synchronous motor in the positionless control system, a new method of position sensorless low-speed control of the permanent magnet synchronous motor is proposed. By building a high-frequency injection model of a permanent magnet synchronous motor, the topology of the system is optimized. The non-linear state observer is used to replace the traditional observer, which improves the estimation accuracy and real-time performance of the system. In terms of parameter tuning, particle swarm algorithm is introduced into the control system to realize the dynamic tuning of system adjustment parameters, so that the system can adapt to a variety of complex working conditions. And verify the overall function of the permanent magnet synchronous motor low-speed control system based on the sensorless position on the hardware platform, and pass the overall verification of the motor start-up characteristics, load and speed drop characteristics. The research results show that the low-speed control system of permanent magnet synchronous motor based on PSO(Particle Swarm Optimization) theory can run smoothly according to the predetermined speed, and has good anti-disturbance performance, which can meet the control requirements in practical applications.
