This book presents the LPV (Linear Parameter Varying) modeling, identification and control with fault tolerance mechanisms of a Twin Rotor MIMO System (TRMS). The non-linear model of the TRMS is transformed into a quasi-LPV model and then approximated in a polytopic way. The model parameters are calibrated by means of a non-linear least-square identification approach. Once the calibrated model is obtained, a simulator is built and validated against real data. Using the LPV Linear Matrix Inequalities (LMI) pole placement approach, an LPV observer and an LPV controller are designed and tested...
