永磁直线同步电机一阶速度抗扰动控制
A Disturbance Rejection Control of First-oder Speed for Permanent Magnetic Linear Synchronous Motors
摘要
Abstract
For PMLSM direct driven mode,multiple disturbed forces,including load force,friction and magnetic resistance, are acted directly on the rotor of PMLSM without any cushioning, so that they affect the speed stability of PMLSM. This paper presented a PMLSM speed control strategy with disturbance rejection, that was based on the expansion state observer used to observe multiple disturbed forces in dynamic process of PMLSM speed,a tracking differentiator(TD) and nonlinear state error feedback(NLSEF). The disturbance can be compensated,thus the first-order speed control with disturbance rejection of PMLSM can be achieved.关键词
