Abstract
This paper proposes a general synthesis framework to attenuate disturbance responses which are caused due to switching. The objective function to be minimized is the worst-case L2 gain from the past disturbance to the future output. Moreover, we formulate the problem in a general manner so that controller switching is a special case. The compensation is composed by feedforward control inputs in addition to state assignment. A necessary and sufficient condition for synthesis is given in terms of LMIs. It follows that solutions can be obtained efficiently. The effectiveness of the proposed method is examined by using an example.
