Abstract: To improve the precision and stability of the scanning swing mirror control system and address the shortcomings of traditional control algorithms in dynamic response and static control, a composite control algorithm is proposed. This algorithm combines feedforward PID control with dual closed-loop control to form a novel composite strategy. Simulation results demonstrate that, compared to traditional methods, the proposed compound algorithm achieves a significantly shortened convergence time and an effectively reduced overshoot, leading to substantial enhancements in both dynamic and static performance of the swing mirror control system. The composite control algorithm significantly elevates the comprehensive performance of the scanning swing mirror, providing a reliable control solution for its operation.
