Анотація


A speed-regulating system of BLDCM has been designed on the basis of the expert system. It involves nonlinear optimization and PID controller design. The design method is improved through the linear fitting of piecewise function and expert PID controller. The function of PID controller is enhanced according to the error of motor rotating speed. A real experiment has been conducted, and the output demonstrates that this controller is robust and reliable.
