Embodiment Construction
[0048] The present invention will be further described below in conjunction with the accompanying drawings.
[0049] combine figure 1 , the fuzzy adaptive control system of the switched reluctance motor of the present invention is a closed-loop system, including a fuzzy adaptive fractional-order PI controller 1, a PWM module 2, an asymmetrical half-bridge drive circuit 3, a switched reluctance motor motor 4, and a position detection module 5. Current detection module 6, torque calculation module 7 and speed detection module 8, wherein the fuzzy adaptive fractional-order PI controller 1 includes a derivative operation module 9, a fuzzy controller 10, a fractional-order PI controller 11 and a controlled object 12, such as figure 2 shown.
[0050] The fuzzy adaptive fractional-order PI controller 1 is used to process the speed error and its rate of change, and output a given torque value through PI adjustment;
[0051] The PWM module 2 is used to determine the conduction inte...
