dc.description.abstractThis thesis presents a robust control strategy for gas turbine systems using a cascade control structure designed to withstand sensor faults and time delays. The study focuses on the combustion chamber subsystem, where temperature regulation is critical to system safety and efficiency. A mathematical model with two interconnected loops : temperature and gas flow is developed to simulate sensor failure and delay scenarios. To ensure system stability under these conditions, the Lyapunov-Krasovskii functional method combined with Linear Matrix Inequalities (LMIs) is applied to derive sufficient stability conditions. The proposed approach allows for the synthesis of a state-feedback controller capable of maintaining performance despite sensor inaccuracies and communication-induced delays. Simulation results confirm the effectiveness of the control design in stabilizing the system and mitigating the effects of faults.
