摘　　要：针对一类失配的不确定关联大系统 ,基于变结构控制理论和局部模型跟踪原理 ,提出了利用左特征向量设计切换面的方法 ,并结合 Lyapunov稳定性理论和矩阵对角占优性质 ,设计了这类失配不确定关联大系统的变结构局部模型跟踪控制系统。该方法突破了变结构不变性条件的限制 ,使被控对象的关键状态稳态无误差地跟踪参考模型 ,提高了这类关联大系统的稳定跟踪特性 。In order to make the key state variables of a plant track the variables of a reference model, partial model following control (PMFC) was proposed for interconnected large scale system with unmatched uncertainties. Based on variable structure control (VSC) theory, a switch surface was chosen by left eigenvalue, and partial model following control system was realized to ensure zero-error steady following according to Lyapunov stability theory and matrix theory. For interconnected large scale system, adopting PMFC overcomes the difficulties of meeting the requirement of strict matching condition in perfect model following, and the following performances of the key state variables are improved. An illustration example was given to verify the method.
