摘要
针对近空间飞行器在高超声速飞行阶段对于控制器的强鲁棒性要求,提出了一种适用于近空间飞行器的单向滑模控制方法。该方法通过对于传统滑模进行结构上的改进,并引入单向辅助面和正不变集2个概念,从而增强了滑模控制方法的鲁棒性能。与传统滑模控制方法不同,文中单向辅助面使得滑模控制器的设计一定程度上脱离了切换面的桎梏,令一些不稳定的超平面也能够参与到控制器的设计过程中,并获得了新的控制性能,通过理论分析和仿真验证表明了该方法的强鲁棒性能。
For a near space vehicle in hypersonic flight phase for robustcontroller,one-way sliding mode control method is proposed for a near space vehicle.The method for the traditional sliding mode improves the structure,and the introduction of Unidirectional Auxiliary Surfaces and positive invariant set of 2 concepts,so as to enhance the robustness of sliding mode control method.Different from the traditional sliding mode control method,this papermakes the UAS sliding mode controller is designed to a certain extent from theshackles of the switching surface,make some unstable hyperphnes can alsoparticipate in the design process of the controller,and obtained a new control performance,strong robustness performance of the method is demonstrated through theoretical analysis and simulation verify.
