Fuzzy Control Of Dc Drive Design

This dissertation majorly researchs and designs full digital DC driving system with FUZZY control .it makes a scheme argumentation firstly ,analyzing the PID algorithm and FUZZY control algorithm the ordinary digital pulse trigger algorithm and the double remainder method of pulse trigger in detail ,and FUZZY control and the double remainder method are put forward to settle the under-mentioned problems ,namely ,the new viewpoint and the task having finished in this dissertation as follows:(1) In rder to overcome the influence of DC motor's parameter changing with time and nonlinear on the control system performance, this dissertation adopts FUZZY control as outside regulator and PI control as inside regulator in double regulators of the full digital DC motor driving system design;.(2) Aiming at the pulse trigger reliability of the ordinary d igital pulse trigger being low and leaking the pulse or the order of pulse confusion ,this paper adopts the double remainder algorithm with short response time high pulse trigger reliability good adaptability and anti-jamming ;(3) This dissertation adopts TMS320LF2407 which has good performance as major control chip this chip has power function with fast calculation capability ,and accomplishes the software and hardware design in the DC motor driving system with FUZZY control;(4) This dissertation also puts emphases on anti-jamming in hardware and software ;(5) After having designed the sample of full digital DC motor driving system with FUZZY control, a lot of experiments are performed to verify the performance and settles problems during experiment .the result of experiment proves the feasibility of design .
