Abstract

In view of the nonlinear characteristics of aircraft variable frequency AC digital voltage regulator system, the fuzzy control is combined with PID control to design the control algorithm of digital voltage regulator and construct a multi closed loop feedback control strategy. The design method and modeling process of fuzzy PID controller are introduced, and then the simulation model of fuzzy PID control is built in Simulink. The voltage regulation performance of the proposed control and the traditional PID control are compared under different operation conditions. The results show that the dynamic and steady-state performances of the regulator under fuzzy PID control are better than those of the traditional PID control. Finally, the experimental verification based on dual DSP hardware platform is carried out, and it is cross-linked with the typical electrical load of a type of aircraft. The experimental results prove the correctness and effectiveness of the designed controller.
