Adaptive fuzzy control with H∞ performance for microturbine

As the gas turbine dynamic model is very complex and has large uncertainty, the adaptive fuzzy control strategy of speed with H∞ performance is proposed via linear matrix inequality technique for MTG based on Lyapunov stability theory. At the same time, a robust adaptive compensator is derived to eliminate the effect of the approximation error and external disturbance and guarantee the closed-loop system stability and good tracking performance. Simulation results show that the proposed hybrid control strategy can satisfy the requirement of the real-time control, speed tracking and suppression of electromagnetic disturbance. It is easy to be implemented in engineering.
