Unknown Input Sliding-mode Observer Design for a Drum-type Boiler
نویسندگان
چکیده
In this paper we propose a gain matrix selection procedure for a class of full order unknown input observers (UIO). These kinds of observers employ sliding-mode principles to force the observation error into the sliding surface. Then, the error starts a sliding motion along the surface until it asymptotically converges to zero. Although this method exhibits good performance, there is not any explicit and direct method to compute the observer gains. In our approach, we consider the problem of finding the observer gains in the terms of linear matrix inequalities (LMIs). The simulation results for an industrial drum type boiler demonstrate the effectiveness of the proposed approach.
