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.
