Turbogenerator self-tuning automatic voltage regulator

Results are presented from new self-tuning controllers for turbogenerators. Simulations and micromachine tests have been successful, with a prototype self-tuning controller being manufactured. This is intended as a direct replacement for a conventional AVR, so a more conventional fixed parameter controller is also considered, serving as a comparison of performance. Typical results are given for normal set point changes and fault dynamics. An additional modification which could be introduced if a power signal were available, a form of power system stabiliser, is also covered. These new controllers are shown to have good potential for practical application.
