1434-9922 near systemsMany problems in decision making, monitoring, fault detection, and control require the knowledge of state variables and time-varying parameters that are not directly measured by sensors. In such situations, observers, or estimators, can be employed that use the measured input and output

Introduction,decision making, monitoring, and control require the knowledge of the variables, i.e., states and parameters of the system involved. In practical situations, measuring all these variables may not be possible due to technical or economical reasons. Therefore, the . of states and parameters in dynamic

Observers for TS Fuzzy Systems,asured states based on the system model and the available input-output data. This chapter introduces the concept of observers used for TS fuzzy systems and reviews methods for designing observers such that the estimation error asymptotically converges to zero. We also briefly describe observer-based

Cascaded TS Systems and Observers,ibuted systems is considered: cascaded systems. Systems can either be naturally cascaded, or can be transformed into a cascade of submodels by a suitable reordering of the state variables. It is assumed that both the whole system, and also the subsystems are represented by TS fuzzy models, i.e., the

Adaptive Observers for TS Systems,e due to the degradation of parts of the system, actuator faults, or disturbances that should be detected as soon as possible. Therefore, this change has to be considered when designing observers and controllers. In this chapter, methods to design adaptive observers that simultaneously estimate the

Cascaded TS Systems and Observers,cade of two subsystems is presented, together with stability conditions for cascaded nonlinear systems. In the second part, we consider the cascaded stability analysis of cascaded TS systems. Finally, cascaded observer design for TS systems is studied.
