Fractional order fuzzy PID control method for DC/DC converter

The invention provides a fractional order fuzzy PID control method for a DC/DC converter, and relates to the technical field of power system control. The method comprises the steps of 1 calculating the deviation value e (t) between input and output; 2 subjecting the e (t) to an integration link to obtain an output control quantity KiD-lambda e (t); 3 subjecting the e (t) to a differential link to obtain an output control quantity KdDmue (t); 4 searching parameters and storing the parameters, and judging whether the parameters are the last point on a grid or not; 5 performing fuzzy reasoning; 6 performing ambiguity resolution; 7 obtaining an output control quantity u (t); and 8 enabling u (t) to act on the DC/DC converter. According to the invention, the control effect of a controller can be improved, so that the controller has faster and more robust response; the control flexibility and accuracy are greatly improved, the stability of a control system can be improved, and great significance is achieved for imp
