The dataset relates to the following paper:Abolpour, R., Dehghani, M. and Talebi, H.A., 2019. Output feedback controller for polytopic systems exploiting the direct searching of the design space. <i>International Journal of Robust and Nonlinear Control</i>, <i>29</i>(15), pp.5164-5177.<br>Summary: The paper deals with the problem of designing a robust static output feedback controller for polytopic systems. The current research that tackled this problemis mainly based on LMI method, which is conservative by nature. In this paper, a novel approach is proposed, which considers the design space of the controller parameters and iteratively partitions the space to small simplexes. Then, by assessing the stability in each simplex, the solution space for design parameters is directly determined. It has been theoretically proved that, if there exists a feasible solution in the design space, the algorithm can find it. To validate the result of the proposed approach, comparative simulation examples are given to illustrate the performance of the design methodology as compared to those of previous approaches.
