Design of Adaptive Control System for Multi-modal Aircraft

Abstract

Multi-modal aircraft is a variable structure system with great application value. With the development of cruise missile technology in recent years, multi-modal variable structure control technology and mathematical modeling have become the main research contents. Aiming at the problems of inaccurate modeling, strong coupling, large mutation and nonlinearity in the modeling process of multi-modal aircraft, this paper adopts the KANE method for mathematical modeling, and proposes a model based on an improved generalized extended state observer. Predictive control algorithm to achieve effective control of multi-modal aircraft. When the multi-modal cruise missile faces complex disturbances, the control system can effectively control the aircraft. Finally, it is verified by simulation that the control system has certain robustness and adaptability.
