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
