针对吸气式高超声速飞行器动力学模型,设计一种基于预设性能的反演鲁棒控制器。在反演控制的设计框架下,基于预设性能函数对跟踪误差进行转换实现对收敛速度、超调量的约束。为解决反演控制鲁棒性能较弱的问题,基于改进的反正切微分器构造了一种新型干扰观测器,对模型中的不确定项进行估计。仿真实验表明,该方法能够较好的实现对控制系统瞬态性能的约束。

A prescribed performance back-stepping robust control approach is presented for the dynamical model of generic air-breathing hypersonic vehicle. A performance function characterizing the error convergence rate and maximum overshoot is designed for the tracking error transformation under the back-stepping framework. To enhance the robustness of back-stepping controller, the novel disturbance observers based on the modified arctangent-based tracking differentiators are devised to estimate the uncertainties of model. The simulation results show that the transient performance of the control system can reach the prescribed performance.
