摘要
基于 T S模糊模型,针对状态可直接测量的模糊系统,通过把其描述为一族局部状态空间模型,提出了一种新的观测器离散设计方法。该方法对每一个局部状态空间模型,分别对失效的传感器进行观测器设计,从而重构出失了效的传感器不能测量到的状态而实现容错控制。本文方法易于设计,便于实时实现,克服了常规设计方法的复杂性,最后把该方法应用到某飞机横侧向飞行容错控制,证明了其有效性。
In engineering applications, systems are really nonlinear in nature. We propose a fault tolerant controller based on the Takagi Sugeno fuzzy model of nonlinear systems. In our new observer design of discretizing, we describe the fuzzy system as a family of local linear models. In engineering applications, sensor failures often occur. In section 3, we discuss how the unavailable state of one failed sensor can be reconstructed. Fig.2 shows the simulation results of fault tolerant control of lateral flight of a certain aircraft and they show preliminarily that our new observer design of discretizing is effective.
