Design of LQG/LTR Controller for Dynamic Stability Improvement of AC/DC Power System

This paper presents results of a robust linear quadratic Gaussian with loop transfer recovery (LQG/LTR) damping control scheme for improving the local mode oscillations of AC/DC power system. It is shown that the suggested method can improve the system stability and it can perfectly consider the unknown disturbances of the power system. The performance of the designed system is assessed in the frequency domain and via appropriate time-domain simulations.
