Robust active controller of hypersonic vehicles in the presence of actuator constraints and input delays

摘要

This paper focuses on the problem of robust active control algorithm for the flexible air-breathing hypersonic flight vehicle in the presence of state, actuator constraints and input delays. Constraints in the model, as well as input time delays, are the highly challenging problem in the design of flight control system. Based on linear parameter varying (LPV) model obtained by Tensor-Product model transformation technology, a novel parameter dependent robust model predictive control (PD-RMPC) algorithm with explicit time-delay compensation is presented. Since developing the robust tracking controller with delay compensation, the proposed method is much less conservative and better performance. Finally, the numerical simulation results prove availability of the proposed method.
