A performance-oriented, non-iterative, local design method for mismatch-based anti-windup compensators

This paper proposes a local and - in contrast to existing synthesis approaches - non-iterative and performance-oriented design method for linear, full-order, mismatch-based anti-windup compensators which is applicable to control systems with unstable plants. Non-iterative means that the anti-windup compensator is found by solving a convex optimization problem. Hence, initial guesses or trial-and-error loops can be avoided leading to a significant simplification of the design process. Performance-oriented means that the L₂ gain of a system characterizing the degradation from the unconstrained linear performance is minimized. Two examples are considered to demonstrate the new design method.
