Abstract

A fuzzy logic control allocation algorithm is proposed to deal with the control allocation problem in the compound control system of air-to-air missile. The control law of compound control variable is designed by dynamic surface control method. In the design process the extended state observer is used to estimate the lumped uncertainties, and the smooth second-order sliding mode control algorithm is adopted to design the control law. They achieve the goals of improving robustness and weakening chattering phenomenon. The fuzzy logic control allocation algorithm is used to break the compound control variable into direct thrust control command and fin deflection control command. In order to test the control effect of the designed compound control system, the comparison simulation experiments are performed for both the compound control system based on fuzzy logic control allocation algorithm and the traditional aerodynamic force control system. Simulation result comparison shows that the designed compound control system has better control effect.
