This thesis in2 volves in simulation research of P I ( Proportion Integration) adjustment, speed loop modulation and dq / trans2 form ation, gaining SVPWM ( Space Vector Pulse W idth Module) waves and main loop based on module structure under the environm ent ofmatlab / SIMUL INK. gle, revolution speed of rotator and rotating of torque. control and velocity modulation of PM SM was realized. Scope space was used to observe the stator current, rotating an2 Through adjusting the model param eters timely, vector The simulation results indicat that vector control system has the characteristics of fast speed up, strong overload capacity and ideal speed adjustment.
