Design and Implementation of a DC Motor Control Simulation System Based on Microcontroller

1. Control Requirements1. Start/Stop Control: A light touch on the “Start/Stop” button allows for flexible switching of the motor’s operational state. Each time this button is pressed, the motor accurately toggles between running and stopping states, making operation simple and efficient;2. Direction Control: The “Forward/Reverse” button allows for easy changes in motor direction. Each press of the button instantly switches the motor between forward and reverse rotation, meeting the directional needs of different working scenarios;3. Acceleration Adjustment: Pressing the “Accelerate” button will automatically fine-tune the PWM pulse duty cycle, increasing it by 5% each time. This precise adjustment mechanism enables a linear increase in motor speed, ensuring smooth and stable speed changes.4. Deceleration Adjustment: When the “Decelerate” button is pressed, the system will decrease the PWM pulse duty cycle by 5%, achieving a smooth reduction in motor speed, ensuring stable operation during deceleration and avoiding sudden speed changes.2.
