LMI-Based Robust Control Strategy for Wind Energy Conversion System through Communication Network

Many processes include time-delay and parametric uncertainties phenomena in their inner dynamics. The existence of time-delay and parametric uncertainties usually deteriorate the performance of closed-loop systems and may be a source of instability. This paper presents LMI-based methods for designing a robust controller for Wind Energy Conversion System taking input uncertain time-delayed communication network and parametric uncertainties into account. The robust design methods handle the parametric uncertainties and provide both stability and performance guarantees. The method was chosen as they are based on time-delay and structured uncertainty description, which makes the controllers less conservative than unstructured uncertainty description, making this description favorable. After detailed theoretical analysis, Simulation results show the capability of the proposed approach to enhance the performance of the wind energy conversion system with parametric uncertainties and uncertain time-delayed communication network.
