This course is primarily designed to achieve PWM speed controller for forward and reverse, acceleration, deceleration, and stop such an operation. And to achieve the circuit simulation. To achieve system, microputer control, in the design, using AT89C51 microcontroller control system as a whole, the core of the control circuit, acpanied by a variety of shows, drive module enables the motor speed parameter display and measurement。 from the mand input module, Optical isolation module and Hdrive module. With the standalone keyboard with a break as a mand input, singlechip in the process control, continuing to the optical isolation circuit to send PWM waveform, Htype motor driving circuit to plete positive inversion control. In the design, using PWM speed mode, by changing the PWM duty cycle to change the motor armature voltage, so as to realize the speed of the motor. Design of the control sy
