摘要
针对时滞不稳定系统,提出了一种基于模糊逻辑的设定值加权PID控制方法。采用以设定值跟随误差和误差变化为输入的二维模糊逻辑控制器来在线实时调整加权参数值,使系统获得更好的目标值跟踪特性。仿真实验结果表明这种方法具有较好的动态性能指标。
Based on fuzzy logic,a set point weighted PID control method is proposed for time-delayed unstable system.A two-dimensional fuzzy logic controller with error,and error derivative followed by set-point for its inputs are designed to adjust the weighting parameter values in real-time on line.Thus the system has a better target tracking characteristics.Simulation experiment results showthat the method is of good performance.
