Active disturbance rejection fuzzy control of MTG fuel pressure

The fuel pressure control system is an important component of microturbine generator system. In order to keep pressure constant in the fuel-storing tank and eliminate the harmonic interference due to existing drive system, a active disturbance rejection fuzzy control scheme is proposed. The algorithm combines active disturbances rejection control technology with fuzzy control technology, and solves several problems of fuel pressure control, such as microturbine loading or unloading uncertainty, drive system disturbance, stability and quick response in start-up and operating. Results of simulation and experiment were shown that active disturbances rejection fuzzy control had improved rapid tracking and against strong interference effectiveness.
