无刷直流电机调速系统转矩脉动抑制方法研究
Research on torque ripple suppression method for BLDCM speed control system
摘要
Abstract
The phase current of BLDCM during the opening period and shutdown period is analyzed. The electromagnetic torque expression is obtained by actual calculation,and then the corresponding electromagnetic torque ripple curve is obtained. The prediction model is divided into model establishment,feedback tuning and performance optimization with current prediction method. The phase commutation current is controlled in a stable state to suppress the torque ripple. The simulation and practical experiment results show that the BLDCM speed control system has the advantages of small torque ripple,fast response speed,etc.关键词
