Abstract

Abstract:
In this paper, a method for optimal proportional-integral-derivative (PID) controller
design is proposed to improve the performance of the turbo generator automatic voltage
regulator (AVR). The method utilizes the genetic algorithm (GA) to find the controller
gains that minimize a synthesized performance index. The performance index considers
the system response to both set point and voltage disturbance. Furthermore, the closed
loop robust stability is guaranteed by imposing a finite bound on the maximum
sensitivity function. Simulation tests are provided to validate the effectiveness of the
proposed scheme.
