The Design and Evaluation of a Microcontroller-Based Electromechanical Position Control System
This paper develops an integrated electromechanical position control system with an embedded microcontroller platform, combining signal processing, control, actuation, and mechanical design. The system operates through a sensing, control, and execution loop for automatic position adjustment. For hardware implementation, the system includes a signal conditioning circuit, a power drive circuit, and a mechanical structure for sensor processing, actuator control, and component integration. For control implementation, a proportional controller runs on an Arduino microcontroller for closed-loop position adjustment. Then, its performance is evaluated through circuit, control, and prototype simulations under different inputs. The results indicate that the prototype achieves a relative tracking error below 2% across the tested positions, with an average response time of 0.82 s under the 90° reference input. Moreover, the integrated hardware and software modules achieve basic closed-loop position control in a low-cost electromechanical prototype system.
