| Abstract: | An adaptive fuzzy PID controller based on variable universe is applied to the excitation system of synchronous generator.Its structure design and factor selection are explained and its control law is given.The terminal voltage and the voltage differential are used as its inputs and the proportional,integral,differential coefficients are adjusted in real time by fuzzy treatment.The concept of variable universe is adopted to improve the parameter adjustment accuracy by selecting suitable control-expansion fac... |
