本文介绍了用变量结构系统法(VSS)设计线性状态观测器的新方法,它与传统状态观测器的设计方法不同。变量结构系统法的优点,在状态控制器的设计应用中得到了充分的证明,如具有较好的品质指标和鲁棒性等,并举例证明和介绍了具体的设计步骤。 This article describes a new method for designing linear state observers using the Variable Structure Systems (VSS) approach, which is different from the traditional state observer design method. The advantages of the variable structure system method are fully proved in the design and application of the state controller, such as good quality indicators and robustness, and illustrate and introduce the specific design steps.
