本文首先研究了在采用微处理器的直流电机控制器中应用模糊算法的理论基础,并与其它微处理系统做了比较。其次重点介绍了该模糊控制算法在典型的单片机控制直流拖动系统中的应用,其中硬件设计包括在proteus所搭建的硬件平台上所做的硬件仿真方案。最后在MATLAB环境中对Fuzzy阶跃响应曲线的动态与稳态特性进行了介绍,并在调节时间、超调量、稳态误差等方面指明了模糊控制算法的优越性。同时,也探讨了模糊控制算法的局限性。 In this paper, the theoretical basis of applying fuzzy algorithm to DC motor controller with microprocessor is studied and compared with other micro-processing systems. Secondly, this paper mainly introduces the application of the fuzzy control algorithm in a typical single-chip microcomputer controlled DC drive system. The hardware design includes the hardware simulation program made by Proteus hardware platform. Finally, the dynamic and steady-state characteristics of the fuzzy step response curve are introduced in the MATLAB environment, and the superiority of the fuzzy control algorithm is indicated in terms of adjustment time, overshoot and steady-state error. At the same time, the limitations of fuzzy control algorithm are also discussed.
