  • As discussed in Lecture 20, a process is better described in terms of a set of plants centered around a nominal model. The robust stabilization problem is concerned with finding non conservative conditions on the stable nominal closed loop system that guarantee the stability of all possible closed loop systems. An equally important problem is the robust performance problem which is concerned with finding non conservative conditions on the nominal closed loop system that guarantee that the performance is met for all possible closed loop systems.
