| Abstract: | A new means of observation of stator flux linkage of permanent magnet synchronous motor based on kalman filter is proposed, then the design theory of kalman filter is emphasized. Finally the means is applied to a control system of direct torque control for permanent magnet synchronous motor and the result of simulation show that the new means has better observation result of flux linkage. It can entirely eliminate direct current departure and accumulating error. |
