Reasonable selecting motor capacity is important; induction motor capacity can be determined by its speed and load torque. In this paper, a method for simultaneously estimating motor load torque and speed using extended Kalman filter is presented, a state space model of induction motor including speed and load torque states is established; based on this model, EKF is used to implement the estimation of speed and load torque of induction motor. Simulation and experiment results demonstrate that the proposed method can simultaneously estimate speed and load torque with higher accuracy |
