| Abstract: | To improve the performance of induction motor vector control system,parameters estimation on line and speed controller frame are very important.A novel parameters estimation based on the multiple innovation least squares is proposed,the rotor time constant and the stator resistance of induction motor can be estimated from the stator currents,stator voltages and speed.To further improve the static and dynamic system performance,a speed controller is designed by using Anti-Windup technology,a back-calculation... |
