基于能量函数的永磁同步电机无速度传感器H∞控制
Speed Sensorless H ∞ Control for PMSM Based on Energy Function
摘要
Abstract
The speed sensorless H ∞ control method for PMSM was researched based on the enerG gy function.In order to control the speed of motor rotator effectively,firstly the Hamilton model of the PMSM was shaped when there was not disturbances,and the rotator speed might reach the expecG ted value.When there were disturbances,a H ∞ controller was designed based on the Hamilton funcG tion.An observer was designed using the method of expansion plus feedback based on the Hamilton function and used to measure the angular speed of rotator,and the speed sensorless shape plus H ∞control were achieved.The simulation results show that the shape plus H ∞ control based on the obG server can estimate the angular speed accurately,and restrain the disturbances of system,and control the rotator speed effectively.关键词
