 abstract = {A major difficulty encountered in the application of linear parameter-varying (LPV) control is the complexity of synthesis and implementation when the number of scheduling parameters is large. Often heuristic ad hoc solutions involve the neglection of individual scheduling parameters, such that standard LPV controller synthesis methods become applicable. The principle component analysis (PCA) based technique of parameter set mapping (PSM) has been proposed as a systematic way for obtaining LPV models with fewer scheduling parameters. However, controller designs based on an approximate model cannot guarantee stability and performance when implemented on the original plant. In this paper, a posteriori conditions are proposed to assess closed-loop stability and performance. Moreover, a possible synthesis approach is sketched based on iterating between convex optimization problems. A two-degree-of- freedom (2-DOF) robotic manipulator is considered as an illustrative example.},

The controller design for complex nonlinear systems using the framework of linear parameter-varying (LPV) systems often leads to high costs in modeling, synthesis and implementation. Interconnected LPV subsystems also yield complex systems. This thesis presents methods for the modeling of complex LPV systems, in the sense of nonlinear as well as interconnected subsystems and introduces improved controller synthesis tools that lead to reduced synthesis and implementation costs.},
