Sliding Mode Control of VTOL Aircraft Based on Stability Criterion
摘要
Vertical take-off and landing (VTOL) aircraft overcome the traditional runway take-off limitations, which has important military value. This paper presents a tracking control strategy based on Huriwtz criterion for VTOL aircraft to realize its stability control. First, the dynamics model of VTOL aircraft is established, and the characteristics of the model are analyzed, so that the system is divided into a minimum phase system describing vertical flight dynamics and a coupled underdriven non-minimum phase system describing horizontal and rolling dynamics. Then, the controller is designed for two subsystems respectively. According to the parameters design of the controller, the stability criterion is adopted to realize the stability control. Finally, simulation experiments are used to confirm the efficiency of the suggested strategy.
