无刷直流电机PI控制系统的设计及分析
Design and analysis of PI control system for brushless DC motor
摘要
Abstract
Traditional software controllers have such problems as slow running speed, low precision, poor immunity from interference, and high cost. A PI control system of BLDCM is presented based on complex programmable logic device to solve these problems. This system is composed of all hardware and adopts trapezoidal commutation control strategy. It has advantages of high response speed and strong immunity from interference. At the same time, the effect of different PWM modulation modes on armature current and electromagnetic torque of brushless current motor is analyzed, and the H-PWN—L-PWM modulation mode is selected to achieve the desired control effect. Finally, an experimental platform is built. The driver reaches stable state after 25.6 ms at the set speed of 2500 r/min. The results show that the system has good dynamic response performance.关键词
