Hybrid approach for the design of robust control systems

Abstract

ABSTRACT This paper addresses the problem of robust controller design for stable finite dimensional linear time-invariant systems (stable FDLTIS) within the framework of model reference schemes. The proposed methodology applies to both continuous and discrete-time systems and employs two distinct design stages: (1) design of the feedforward controller and (2) design of the feedback filter. Algebraic and topological concepts are utilized to tackle several important design issues including stability, performance and robustness. Finally, two examples are given to demonstrate the power of the design method.
