英文摘要

      Aero engine turbine power generator is a typical nonlinear and time-varying system with intense disturbances, high uncertainty and model complexity. It is difficult to achieve a good performance by traditional control methods. Adaptive fuzzy control method based on variable universe has advantages such as no need for exact models, fast response, and high precision and strong robustness. In this paper, the control algorithm is applied to an aero engine turbine power generator. Firstly, the corresponding structure design and contraction-expansion factor selection of the controller are provided in details, and then the control law is given. Finally, by the field test and trial production, it is proved that the control scheme is reliable and effective.
