Abstract:Considering the fact that it is difficult for the conventional PID controller to meet control request in the aircraft control process, we designed a normalized feedforward-feedback controller system. Furthermore, the hybrid optimization algorithm that combined the chaos optimization algorithm and the conjugate gradient method was used to search for the optimum parameters of the feedforward-feedback controller system. Simulation experimental results and experimental analysis proved the superiority of the hybrid optimum feedforward-feedback controller, which showed better dynamical and steady behavior, strengthened the fitness and robustness of the system, and weakened the blindness to selection of learning factors and high dependency on experience.
