Abstract:
To solve the flight control problem for unmanned hypersonic vehicles, a novel intelligent optimized control method is proposed. A flight control system based on integral separated proportional-integral-derivative (PID) control is designed for hypersonic vehicle, and an improved shuffled frog leaping algorithm is presented to optimize the control parameters. A nonlinear model of hypersonic vehicle is established to examine the dynamic characteristics achieved by the flight control system. Simulation results demonstrate that the proposed optimized controller can effectively achieve better flight control performance than the traditional controller.
