超音速靶弹的鲁棒自适应反演控制系统设计

摘要

Aimming at the problems that model uncertainty of supersonic cruise missile and external airflow interference, an robust adaptive backstepping controller is proposed for the system. An non⁃matching uncertainties supersonic target missile nonlinear dynamics model is established, Virtual control and actual control are got by using backstepping design, the adap⁃tive robust is introduced in virtual control and actual control to offset system uncertainties. Lyapunov stability theory is used to prove control system is stable. Simulation results show that the designed controller can solve the system uncertainties and ex⁃ternal interference problems effectively and it has strong robustness.%针对靶弹超音速低空巡航的模型不确定性以及外界气流对靶弹产生干扰等问题，研究了一种适用于超音速低空巡航靶弹的鲁棒自适应反演控制方法。建立了一种非匹配不确定性的超音速低空巡航靶弹非线性动力学模型，利用反演设计法求取虚拟控制和实际控制，并在虚拟控制和实际控制中引入自适应鲁棒项，以抵消系统不确定性的影响。利用Lyapunov稳定性理论证明控制系统稳定。仿真表明，所设计控制器能有效解决系统不确定性及外界干扰问题，具有较强鲁棒性。
