PID Control Algorithm for Helicopter's Three Attitude Angles with MATLAB/Simulink Implementation

The PID control algorithm for helicopter's three attitude angles is implemented using MATLAB's Simulink simulation environment, combined with optimal PID design algorithms to achieve outstanding control performance. It's important to note that the three attitude angles of a helicopter include roll angle, pitch angle, and yaw angle, while the PID control algorithm is an automatic control method widely used in control systems. In this simulation program, we employ MATLAB's Simulink tool for system modeling and simulation. The implementation features three separate PID controllers for each attitude angle, with carefully tuned proportional, integral, and derivative gains. Through integration with optimal PID design algorithms such as Ziegler-Nichols or advanced optimization techniques, we achieve highly satisfactory control results. The successful application of this algorithm not only holds significant importance for helicopter control systems but also provides valuable insights for control system design in other domains. The Simulink model includes blocks for sensor feedback, PID controllers, actuator models, and helicopter dynamics, allowing for comprehensive analysis of system response and stability.
