This project focuses on the design and simulation of a DC motor bi-directional control system without the need for position sensing. Traditional control systems for DC motors typically rely on position sensors to provide feedback for precise control, which adds complexity and cost to the system. In this project, we propose a sensorless control system that utilizes a potentiometer for controlling the speed and direction of the motor, along with a half H-bridge driver for power control. The control system consists of a microcontroller, a half H-bridge driver, and a potentiometer. The microcontroller generates pulse width modulation (PWM) signals to control the motor's speed and direction based on the input from the potentiometer. The half H-bridge driver allows bi-directional control of the motor, enabling both clockwise and counterclockwise rotation. One crucial aspect of the control system is the incorporation of high amperage or short circuit protection in both directions. This protection mechanism ensures the safety and reliability of the system during operation. It prevents excessive current flow or short circuits that may occur due to sudden changes in motor load or other unforeseen circumstances. To evaluate the performance of the proposed control system, a simulation environment using software tools such as Arduino Uno IDE or Fritizng is created. The simulation enables comprehensive testing under various operating conditions and provides insights into the system's behavior, including the effectiveness of the high amperage or short circuit protection. The results of the simulation demonstrate the effectiveness of the sensorless control system in accurately controlling the DC motor's speed and direction while ensuring high amperage or short circuit protection. The system achieves reliable operation by utilizing the potentiometer as a user-controlled input and the half H-bridge driver for power control. This research contributes to the advancement of sensorless control techniques for DC motors, offering a cost-effective and simplified solution with enhanced safety features for various applications.
