Abstract

Focusing on strong nonlinearity and parameter uncertainty in an air-to-air missile body control system

a fractional three-loop autopilot(TLA)of air-to-air missile is proposed based on the analysis of classical TLA. The properties of whole three loops in fractional TLA are analyzed

the differences between the two mentioned TLAs are revealed. The integral time absolute error(ITAE)rule based genetic algorithm(GA)is utilized for the parameter optimization to gain the optimal control system of the air-to-air missile. By the simulation for the two TLAs

the responses both on time domain and on frequency domain are investigated comparatively. The results verify that the proposed fractional TLA is endowed with the better time domain response and wider stability margin in frequency domain than the classical TLA under the same parameter optimization.
