Control Synthesis for Linear Parametric Time-Varying Systems

摘要

Over the past decade, several multivariable design techniques have emerged thatprovide controllers for a prespecified performance and uncertainty level. A promising approach is H-infinity/mu-synthesis, having the feature to incorporate both design specifications and knowledge about model uncertainty into the problem set-up. Several approaches use ad hoc schemes and sometimes lack guaranteed stability markings. A method that does not suffer from these drawbacks, called 'Gain-scheduling via LFTs', is the main focus of this report. A complete discussion of the theoretical background is provided in order to appreciate the merits and limitations of the method.
