Abstract
The goal of this work is to present a methodology for the design of controllers by mixed-sensitivity H∞ (S/KS/T) for Lurie type systems. The Lurie problem originally searched for necessary and sufficient conditions for absolute stability. In this work, on the other hand, we are not only concerned with absolute stability problem, but also with performance and robustness of performance of the system. In this sense, we show how to get a controller by the mixed sensitivity technique for Lurie type systems with a single input. Next, we present an example and perform numerical simulations that verify that the suggested controller provides robustness of stability and performance.
