The Design of the DC Motor System
Abstract: In order to solve the problems that the DC motor need to be controlled neatly. The design has developed a set of control system, which is based on AT89S52. The control chip is L298n and we use the pulth width modulation techniques to change speed. We achieve the stop, go, acceleration, deceleration, reverse and display function. The simulation results show that the ability of anti-interference of the system has been strengthened, reliability and practicability of the improved. System to achieve the high accuracy on speed control reaches the performance requirements. The DC motor is widely used in the fields, which ask to start and speed control with high requirements.
Key Words: AT89S52; L298n; PWM control
