Design of a Linear Quadratic Gaussian Controller and a STR Controller for Pole Placement to Control the Voltage of a DC Generator

This paper introduces the design of a Linear Quadratic Gaussian Controller (LQG) to regulate the voltage of a DC generator and compares its performance with that of a self-adjusting regulator (STR) tuned by pole placement. To implement these control strategies, the prototype of a DC generator was used and the mathematical model of the system was obtained using nonparametric identification, thetheoretical basis and design of the two control strategies are presented and the performance of the two controllers is compared using integral error and temporal response metrics. Finally, the results obtained are presented from which the good performance of both control strategies is inferred.
