Article Preview

Abstract:

This paper will introduce the sensorless vector control system of permanent magnet synchronous motor,it adopts the PLL structure to correct motor back electromotive force for the motor rotor speed/position estimation and vector control algorithm to realize speed and current loop control of PMSM.This paper established a mathematical model of the PMSM,design of system software and hardware,the principle of speed/position estimation method and simulation of system in Matlab/Simulink.Finally,it introduces the experiment of whole system in TMS320F2808-based PMSM experiment platform,the simulation and experimental result verify feasibility,fast response and practicability of the system.
