摘要

This article is dedicated to robust output regulation for a class of linear minimum-phase systems with guarantee of asymmetric prescribed performance. Through internal model principle, we first construct a so-called augmented system with the considered system and some designed internal models. Then, we convert the prescribed performance robust output regulation problem into the prescribed performance robust stabilization problem of the augmented system with a series of input and coordinate transformations. Furthermore, by combining the existing technique to robust stabilization and the nonlinear mapping method, we design a state feedback controller to solve the prescribed performance robust stabilization problem. Then, we can synthesize the other controller based on the above one to make sure the regulated error of the original system converges to zero and the asymmetric prescribed performance is achieved. Finally, effectiveness of the designed controller is confirmed with an example.
