基于有限时间控制的高超声速飞行器控制律设计
Control law design of hypersonic vehicle based on finite-time control
摘要
Abstract
A control method based on finite-time control technology is proposed for hypersonic vehicle flight control. According to the characteristics of the hypersonic vehicle longitudinal mode, velocity control and altitude control are considered as two subsystems to design controllers respectively. The design of velocity controller and altitude controller is conducted by combining nonlinear dynamic inverse control with finite-time control technique. The engine dynamics is considered during velocity controller design and the velocity can converge to a desired value in finite time under the proposed controller. In order to control flight attitude, first, a finite-time controller is designed for flight-path angle to make it converge to a desired value in finite time, and then according to the one to one correspondence between flight-path angle and altitude, the altitude rapidly converges to a desired value. The simulation results demonstrate that the method is valid.关键词
