| Abstract: | The characteristic and principle of the L298N has been introduced in this paper, and it proposed the design plan of motor PWM control system based on L298N, designed the motor speed regulation system circuit. And it emphasizes on the way for carrying out PWM signals based on MCS-51 software, and this paper still provides a method of DC-motor speed regulation by way of taking count of data and time delay by software. Experience proved that the system have high stability, it can meet the needs of DC motor regulation. |
