摘要
Abstract
The disturbance observer for permanent magnet synchronous motor (PMSM) can effectively restrain the external torque disturbance.Since the parameters of PMSM are time-varying and uncertainty,the performance of disturbance observer declines.A recursive weighted least squares estimation was used to identify the moment of inertia after change.The corrected moment of inertia was used to the disturbance observer.The simulation results showed that this method could precisely identify the moment of inertia online.The method improved the ability of motor to restrain external torque disturbance when the load change.关键词
