摘要

A switching control scheme based on the modal division of the flight envelope is studied in this work, which aims to address the problems of modal transition, unknown aerodynamic parameters, and external time-varying interference in the wide-area climbing of combined power aerospace vehicles. The results of modal division and the process of modal transition are obtained through the analysis of the aerodynamic and thrust characteristics of aircraft. The aerospace vehicle switching system is established on the basis of switching signal design. Then, the terminal sliding mode soft-switching control strategy is designed to ensure the smooth modal transition, wherein the neural network and nonlinear disturbance observer are used to address system uncertainty and external time-varying disturbance. The stability of the closed-loop switching system is analyzed by using the multi-Lyapunov function method, and the effectiveness of the proposed method is verified by simulation results.
