Abstract

The paper compares several methods for robust state-feedback controller design via LMI for a two tank coupled system and discusses qualities of the respective LMI solutions. LMI approach is used to design a controller guaranteeing quadratic or parameter dependent robust stability, H₂ and H_inf performance specification for uncertain linearized model of two tank system. The results obtained using LMI and SeDuMi solvers are compared.
