Research on Rotor Resistance Estimation for Induction Machines Based on Reactive Power Reference Model

According to the problem of reducing the robust control for indirect-field-oriented control of induction machines with uncertain rotor resistance, an estimation method of rotor resistance based on reactive power reference model is addressed. The estimation procedure is carried out independently of the state resistance, load torque, and rotor speed changes. The paper analyzes the stability of the estimation method last. Finally, the validity and practicability are verified by the simulation results.
