摘要
We develop a data-driven and real-time test for candidate controllers' ability to meet given McFarlane-Glover loop-shape specifications. The proposed test provides a data-driven method to improve robustness of closed-loop systems by eliminating controllers that past collected data have proved to fail to meet loop-shape specifications. The test has an important property that many candidate controllers (not necessarily active ones) can be tested in real time using evolving real-time plant data collected while others are active. It is shown that controller-shaping in the present work plays a role that is dual to the role of plant-shaping in the model-based H loop-shaping design procedure. A simulation example is provided.
