基于Matlab无刷直流电机控制系统仿真
The simulation of brushless DC motor control system based on Matlab
摘要
Abstract
In order to reduce the design cost and save design time of brushless DC motor ,in Matlab/Simulink environment ,the control principle and the mathematical model of BLDCM are analyzed to conduct research related to control system .In the modular notion of control system ,by the combina‐tion of the isolated blocks and S‐function ,the model of BLDCM can be established .This system is con‐trolled by the speed and current double loop .Through a classical PID joined to the speed loop ,the ad‐justment of speed achieves smoothness .And a current controller is completed in the current loop on the principle of hysteresis current track PWM inverter .The simulation results prove that the system has good static and dynamic charactertics ,and verify the rationality and validity of this method .By studying the simulation model of BLDCM based on Matlab ,a new approach for designing and debug‐ging motors is provided .关键词
