This paper presents a hybrid control strategy to avoid the basic trade-off between performance and robustness for individual controllers. The hybrid control strategy utilizes a robust controller for guaranteed robustness and adequate performance when the plant model is not well known and/or in the presence of significant disturbances, and employs an adaptive controller for high performance after sufficient system information has been collected. Based on traditional dwell-time approaches, a coordinated dwell-time approach is developed and incorporated into the hybrid control strategy, which guarantees the global stability of the hybrid system for a class of linear systems, as well as combine the benefits of robust control and adaptive control.
