A Digital-Based Optimal AVR Design of Synchronous Generator Exciter Using LQR Technique

In this paper a new structure for the AVR of the power system exciter is proposed and designed using digital-based LQR. With two weighting matrices R and Q, this method produces an optimal regulator that is used to generate the feedback control law. These matrices are called state and control weig...
