针对线性失配不确定性系统，提出了局部模型跟踪、复合参考模型和控制系统匹配度等概念，研究了局部模型跟踪控制系统的设计方法和复合参考模型的特定结构，证明了系统的最大匹配度。本研究突破了完全模型跟踪条件的苛刻限制，能确保被控对象的输出等关键状态稳态无误差地跟踪参考模型，复现系统的指今输入。
For the linear mismatch uncertainty system, the concepts of local model tracking, complex reference model and matching degree of control system are proposed. The design method of local model tracking control system and the specific structure of compound reference model are studied. The maximum match of the system degree. This study breaks through the harsh limits of the complete model tracking conditions and can ensure that the critical states such as the output of the controlled object can track the reference model steadily without error and reproduce the current input of the system.
