摘　　要：为了解决传统模拟PI控制器参数不易整定以及面对被控对象发生变化时无法在线进行参数调整的问题,引入了忆阻器件实现了控制器参数可在线调整。同时针对忆阻器阻值大小不易确定的问题,引入了模糊算法,将模糊算法与忆阻PI控制器进行结合,设计了一种模糊忆阻PI控制系统,实现了控制器参数的自适应调整。在理论推导的基础上,进行了Multisim仿真与电路实验。结果表明,基于模糊算法的自适应忆阻PI控制系统与传统模拟PI控制器相比,参数可以进行在线调整,具有较强的自适应能力,且基于模糊算法的自适应忆阻PI控制系统可以将系统的超调量降低66.27%,具有更好的跟踪性能。In order to solve the problems that the parameters of traditional analog PI controller are not easy to adjust and the parameters can not be adjusted online when the controlled object changes,memristor is introduced to realize the online adjustment of controller parameters.At the same time,aiming at the problem that the resistance value of the memristor is not easy to determine,a fuzzy algorithm is introduced,and a fuzzy memristor PI controller is combined with the fuzzy algorithm to design a fuzzy memristor PI control system,which realizes the adaptive adjustment of the controller parameters.Based up on the oretical derivation,not only the Multisim simulation was carried out,but also the circuit experiment was conducted.The results show that compared with traditional analog PI controller,the parameters of the adaptive memristor PI control system based on fuzzy algorithm can be adjusted online,and has strong adaptive ability.Moreover,the adaptive memristor PI control system based on fuzzy algorithm can reduce the overshoot of the system by 66.27%,and has better tracking performance.
