how to control speed of the motor by using the rectifer inverter and motor circuit

I have to control the speed of the motor .For this i am using three phase ac rectifier inverter and motor.I have designed the three phase rectifier, and inverter individually now how can i combine these and control the speed of the motor.As we know that by chabging the pwm frequency i can change the spped of the motor theoretically i know the this but i don't have the knowledge of desining this.Could u please help me as early as possible .
