【Abstract】 A control algorithm combining the fuzzy controller with selfadjusting function and the binary function Lagrange interpolating algorithm was discussed. This algorithm is used in a DC motor speedregulating system. The realization process and control characteristics were discussed and analyzed in detail. The selfadjusting function is an index function. According to different instances and requests, the parameters in the selfadjusting function can be adjusted through the keyboard. The burst double Lagrange interpolating algorithm was adopted.A speedregulating experiment was made on a 130SZK05 wide speedregulating DC motor.Its control quality and steadystate quality are greatly improved.更多还原
