Abstract:

Based on the switching multi-mode model predictive control method, the coordinated optimal control of the morphing mechanism, elevator, and thrust of morphing aircraft in the cruise phase is explored. The longitudinal dynamic model and aerodynamic model of longitudinal morphing aircraft are established, and the dynamic characteristics of morphing aircraft under different flight conditions are analyzed. In view of the problem of the transfer between the equilibrium points in longitudinal movement, a multi-mode switching model predictive controller is proposed. This controller can optimize the flight performance by coordinating the morphing mechanism, engine thrust, and elevator, and ensure that the state variables of morphing aircraft do not exceed the preset range under the condition of limited input amplitude and rate. Then, the detailed and feasible solving steps and the method of transforming the optimization problem into quadratic programming are given. Finally, the simulation verifies the effectiveness of the method.
