【正文】 celeration are the four factors in DC Speed Regulation System ， the last two factors already reached well in industry application． But the Stability index does not match the desired purpose． Stability index is that the DC motor running in the precision range on desired speed， even if the system has uncertain disturbance． It is hard to realize because of adaptiveability digital DC Speed Regulation device is not enough when in the condition of the load parameters change unpredictably． Fuzzy control does not need precision mathematic model to conquer the shorting in routine digital DC Speed Regulation． We can bine with the PID adjuster and fuzzy control， focusing on theory research and realization of fuzzyPID pound control scheme， design relevant DC Speed Regulation System was designed in the dissertation． This scheme is based on the core of AT89C51 single chip， appropriate driver circuit and some peripheral circuits， Fuzzy Selftuning PID is the control strategy,This dissertation also introduce the plan of hardware and software， including DC motor control module、 driver module、 examine circuit and so on in detail， if explained the method of control and the thought of software， this system got used to the trend of digital power in the international， used the single micro—puter fully， and improveed the general use of the power． Theoretical analysis and design showed that all performance indexes of Parameter SelfAdjusting Fuzzy Logic PID Controller was in advance of those of the simple fuzzy controller and the conventional PID controller． Especially， the adaptive fuzzy controller is robust． Keywords ： fuzzy logic control(FLC) ； DC Speed Regulation ； stability performance； Single microputer 常州工學(xué)院畢業(yè)設(shè)計(jì)論文 III 目 錄 摘 要 ................................................................................................................................
