英文摘要

      The speed stability of a gasoline generator is an important factor that affects its electrical performances. To tackle this problem, we propose a control system consisting of current feedforward and speed feedback in a closed-loop. The feedback controller is a multimodal controller composed of the fuzzy control, PID and maintain mode. Simulation of speed control is implemented by MATLAB, and the experimental results show that the present controller has superior characteristics in the static and dynamic performances of speed stabilization, in the comparison with the traditional PID scheme. It is efficient in speed regulation for gasoline generator.
