Dean of the Graduate College ii PREFACE The methodology of variable structure with sliding mode is proven to be very successful in controlling uncertain continuous-time dynamical systems. When the system is sampled or purely discrete, the invariance property of sliding mode, which is originally a continuous-time concept, no longer hold and the reaching condition has to be modiied to allow a pse...

The control configuration problem is discussed. A new algorithm is outlined which gives suggestion on feedback and feedforward control structure given a SISO control loop and some extra measurements. The algorithm is based on simple experiments and leads to a model of the process as a directed graph. The method is illustrated on a few common industrial control problems. Copyright c & 2000 IFAC

Consider the generalized control design problem in Figure 1. Here, the objective is to design the controller K, which, based on the measurements y, computes the inputs (MVs) u such that the controlled outputs (CVs) z are kept close to their desired setpoints, in spite of unknown disturbances, varying setpoints and measurement noise(w). However, note that it assumed that we know what to measure ...

Flutter is an aeroelastic instability and can lead to destruction of structures, thus its control important in engineering. A flutter problem classified into fluid–structure–control interaction (FSCI) problems. Conventionally, has been investigated using simple FSCI models. However, these models are sometimes insufficient because their many simplifications (e.g., potential flow, geometry, small...
