Control parameter design for automatic carrier landing system via pigeon-inspired optimization

Abstract

In this paper, a novel control parameter design method is presented for the automatic carrier landing system. To overcome difficulties in the manual parameter adjustment task, the pigeon-inspired optimization algorithm is utilized by converting the parameter design problem to an optimization problem. The modified version is proposed to avoid the lack of the diversity of pigeon population in the basic version. Parameters in the inner loop are optimized by computing the fitting difference between an ideal frequency response curve and the frequency response curve of the optimized control system. To optimize control parameters in the H-dot autopilot and the approach power compensation system, a weighted linear cost function in the time domain is adopted. Series of experiments are conducted to demonstrate the feasibility and effectiveness of our method. Comparative results indicate that out method is much better than other methods.
