A comparative study above two self-tuning controllers with application to the control of synchronous generator excitation system
Incremental comparison of known self-tuning methods for a specific power system application.
The paper compares two self-tuning controllers for synchronous generator excitation control, using recursive least squares estimation. Simulation results show the controllers' performance, but no concrete numbers are provided.
This paper presents two self-tuning control structures synthesized through the minimization of two criterion functions. It is described the computation methodology of the control laws, both being particularized for the case of the synchronous generator's excitation control. The parameters estimator is considered the recursive least square error (RLSE) algorithm. In order to validate the considered control structures, two comparative study cases by computer simulation are presented.
