A non-iterative LMI based PID power system stabilizer
World Automation Congress Proceedings
This paper presents a new method of designing a robust PID power system stabilizer. This methodology provides an exact way to tune PID parameters and find an optimal controller using non-iterative Linear Matrix Inequality (LMI) approach. The uncertainties inherent in the system model is also taken into account in the design process to increase the robustness of the proposed controller. For this purpose, H∞ control theory is employed in a LMI framework to design a PID controller that damp oscillations in power system and makes it robust against uncertainty. The obtained matrix inequality is nonlinear which is converted to a LMI in the proposed framework. The Simulation results show the superior performance of the controller compared to conventional method in tuning of PID controller.
