摘　　要：设计一种基于FPGA平台的模糊免疫PID控制器的硬件实现方式,该控制器将模糊免疫PID算法的抗干扰性、鲁棒性与硬件实现的实时性有效的结合起来,提高了伺服控制系统的性能。首先对模糊免疫PID算法进行了介绍和数学推导,然后采用离线计算,在线查找表的方法实现模糊免疫控制。基于Verilog语言设计PID控制器,完成时序仿真测试。数据表明控制器设计过程合理,仿真结果正确,改善了传统PID控制器的性能,是小型系统智能控制一种新的有效途径。A fuzzy-immune-PID controller based on FPGA was designed by combining good anti-interference and robustness by fuzzy-immure-PID controller with the realtime characteristics built by FPGA.It improved the performance of the servo control system.Firstly,principle and algorithm of the fuzzy-immune-PID controller were discussed and its mathematical deduction was carried out.Then with the off-line calculation,look-up table technology was employed to perform the fuzzy immune control.The PID controller based on Verilg carried out the squential simulation.Expenimental results show that the method is reasonable and has a better performance than the traditional one.The proposed method is efficient to implement intelbigent control strategy to small machines.
