摘　　要：针对沥青路面修复机控制系统,应用模糊控制理论与传统PID控制的原理,设计了一种基于单片机的模糊自适应PID温度控制器.根据沥青路面修复要求实现的功能建立了温度控制系统的近似数学模型,对系统先后进行各种控制仿真,通过仿真发现,系统中模糊整定PID控制算法的动态性能比PI,PID和可积分分离的PID控制的性能要好,且具有较强的抗干扰能力,为复杂系统建模提供了一个有效途径.This thesis, adopting fuzzy control theory and the principle of traditional PID control, has designed a kind of fuzzy-PID(FPID) self-adapting automatically temperature controller based on MCU. An approximative mathematical model of the temperature controlling system has been constituted and simulated with various controlling strategy, according to the demanded function of the running microwave heating asphalt pavement regenerate repairer. From the result of simulation, it suggests that FPID controller, which is of superior anti-jamming capability, overmatches ordinary PI controller, traditional PID controller and integration separation PID controller in dynamic characteristic. Consequently, this simulation of model offers a kind of valid method for the constitution of complicated system.
