This paper described the design of a wind pendulum system, comprising four main components: the operative unit, the data acquisition module, the human-computer interaction interface, and the algorithmic core. By leveraging the principles of the simple pendulum and Lissajous curves, the design enabled the wind pendulum to achieve precise linear and circular motions. The control strategy relied on a fuzzy PID control algorithm, which facilitated closed-loop control and enhanced system stability and performance. The schematic design and PCB layout for the control system were created using Electronic Design Automation (EDA) tools. Furthermore, MATLAB simulations and experimental validation were conducted to assess the performance of the fuzzy PID algorithm in comparison to traditional PID control. The experimental results revealed that fuzzy PID control not only reduced overshoot, shortened settling time, and improved accuracy, but also greatly improved the wind pendulum's ability to execute fixed linear and circular motions with speed and precision. This approach demonstrated the benefits of fuzzy PID in optimizing dynamic system performance, particularly in applications demanding high precision and rapid response.
