摘　　要：针对实现传统模糊PID控制器时,需要建立比例、积分和微分三个模糊控制器,存在模糊规则较繁杂、运算量大、速度慢等问题,提出了以PD模糊控制器代替PI模糊控制器,采用两个PD模糊控制器,并引入FPGA技术,实现模糊PID控制器。通过QuartusⅡ和Matlab联合仿真,比较了基于FBC和SBC实现的模糊PID控制器的控制效果,验证了设计方案的正确性和可行性。In the implementation process of traditional fuzzy PID controller, three fuzzy controllers, including scale, inte- gral and differential controllers, are built. To solve the problems of multifarious fuzzy rules, large calculation quantity, slow speed during the design process of the traditional controller, PD fuzzy controller is used instead of PI fuzzy controller. To realize fuzzy PID controller, two PD fuzzy controllers are applied and FPGA technology is introduced to the design scheme. Through the joint simulation of Quartus Ⅱ and Matlab and the comparison of fuzzy-PID controller based on FBC and SBC, the correctness and feasibility of the design scheme is verified.
