Abstract In order to simplify the control algorithm and further improve the performance of induction motor speed control system, on the basis of space vector theory, the function that the stator voltage vector controls rotor magnetic field and electromagnetic torque is revealed. The principle, method and system are presented in which slip angular frequency variable regulates the stator voltage vector that is implemented by three-phase SVPWM stator voltage, to form the regulation of rotor flux linkage and electromagnetic torque and achieve rapid control of motor speed. This method avoids the coordinate transformation and makes algorithm simple. Simulation and experiment results show that the motor speed control system which is built by this principle has good performance of starting, speed regulation, anti-load disturbance and better robustness to motor resistance variation.

Key words： Induction motor stator voltage vector slip angular frequency speed control robustness
