摘要:

针对高速飞行器机动飞行过程中气动参数随时间变化的问题,提出了一种直/气复合系统的时变控制方法。针对高速飞行器复合控制系统时变模型,在气动力系统中,采用线性二次型调节器设计时变控制律。在此基础上,构建了直接力控制时变受控对象,然后针对该时变系统提出了一种将系统转换为相变量标准型的滑模控制方法。利用Lyapunov-Krasovskii泛函证明了设计的时变复合控制系统的稳定性。仿真表明,与时不变控制器的仿真结果相比,验证了时变复合控制方法的有效性。

Abstract:

The aerodynamic parameters of high speed vehicles vary with time during maneuvering flight. In this paper, a time-varying control method of direct lateral force and aerodynamic force compound system is proposed. For the time-varying model of high speed vehicle compound control system, the linear quadratic regulator is used to design the time-varying control law in the aerodynamic system. On this basis, a time-varying controlled object of the direct force control is constructed, and then a sliding mode control method is proposed to transform the system to the phase-variable canonical form. The stability of the designed time-varying compound control system is proved by the Lyapunov-Krasovskii functional. The simulation results show that compared with the time-invariant controller, the time-varying compound control method is effective.

Key words: time-varying compound control, linear quadratic regulator, sliding mode control, phase-variable canonical form, Lyapunov-Krasovskii functional
