摘要

The use of the pressure signal for speed control of hydrogenerators is investigated. This is done by first analyzing and modeling the plant, assuming an isolated, resistive load. A set of governor gains that give an optimal response to a change in load level using speed feedback is then found. With this response as a benchmark, various methods are analyzed and implemented, utilizing the pressure signal, to improve the response of the system. A state-space observer, designed to attenuate noise on the pressure signal, is discussed. Results show that an observer-based controller using all states as input, as compared to a PID controller, improves the transient response of hydrogenerators, is effective at filtering out the noise on the pressure signal and is more robust to both steady-state pressure and plant parameter variations.
