The torque regulator, flux regulator and speed regulator of induction motor control system are designed based on stator flux-oriented. An improved flux integration algorithm is adopted to eliminate the drift of the DC voltage and the initial value in the pure integrator. The simulation of induction motor control system is achieved by using the MATLAB. Simulation results show that the control system has good dynamic and static properties, which further verify the correctness and feasibility of the design system.

In this paper, a strategy for estimating the induction motor’s rotor speed is proposed. The proposed rotor speed estimation strategy is based on model reference adaptive identification theory. By applying the proposed strategy, the induction motor control system can estimate the induction motor's rotor speed precisely. To improve the rotor speed estimation performance of the system, two methods have been adopt. The speed sensorless control system based on proposed strategy was built with Simulink blocks in Matlab platform. The corresponding simulation results demonstrate that the proposed method can operate stably in the whole range of speed with preferable estimation precision of stator resistance and rotor speed.
