This paper considers the problem of achieving stability and certain ∞ H performances for a largescale system by a decentralised control feedback law. The performance problem is formulated as a standard weighted mixed sensitivity ∞ H problem. Then, to solve the proposed problem a modification of the original weighting functions is presented. Some sufficient conditions are introduced to ensure th...

Both H∞ and 2 H optimizatio...

-A mixed sensitivity H control methodology is tested on a Three-Tank-System laboratory prototype. The methodology is based on a stable precompensator and its dual post-compensator which allows to solve a mixed sensitivity problem. Frequency responses show that it is possible to shape the open loop transfer function by the control parameters. Time responses are given under flow leak, close conne...

From the optimization point of view, an optimum solution of the unit commitment problem with reliability constraints can be achieved when all constraints are simultaneously satisfied rather than sequentially or separately satisfying them. Therefore, the reliability constraints need to be appropriately formulated in terms of the conventional unit commitment variables. In this paper, the reli...
