【Abstract】 This paper proposes two identifiers. One is used to identify stator flux, by which the electromagnetic torque can be calculated. The other discusses dynamical identification of rotor speed under the conditions that the parameters of induction motor are unchanged or partially changed. Then simulation results are given.更多还原
