非线性系统的控制一直是具有挑战性的普遍问题,建立一个通用、易于控制器设计并具有高精度的非线性模型是解决控制系统设计的关键,U模型的起源正是基于这样的认识演变而来的.自U模型被提出以来,已为非线性控制系统设计开创了一个新的研究领域.为此,在总结十年来基于U模型的对象辨识、控制系统设计和鲁棒性研究的基础上,分析已进行的研究工作所具有的优势和所存在的问题,并提出了基于U模型的非线性系统分析和设计的进一步可能的研究方向.
The control of nonlinear systems has always been a challenging universal problem. It is the key to solve the design of control system to establish a universal, easy-to-design nonlinear controller with high precision. The origin of U-model is based on such cognitive evolution Since the U model was proposed, it has opened a new research field for the design of nonlinear control systems.Therefore, on the basis of summarizing the U-model based object identification, control system design and robustness research , Analyzed the advantages and problems existing in the research work, and proposed further possible research directions of nonlinear system analysis and design based on U model.
