摘要
本文针对一般模糊控制系统抗扰动特性较差的缺点，在系统中加入一个干扰估计环节，对不可测量或特性未知的干扰实现前馈补偿控制，以抑制此类干扰对系统输出的不利影响。通过分析和计算机数字仿真表明，按这种结构设计的控制系统，具有很好的抗干扰特性，同时对控制对象的模型化误差也有良好的鲁棒特性。
In this paper,aimming at the weak anti-interference capability of normal fuzzy control system a disturbance estimate unit is presented, which is used to construct feedforward compensating control for non-measurable or characteristic unknowned disturbance to suppress this disturbance effecting on system output. Theoretical analysis and computer simulation demonstrate that the resulting system is provided with perfect antiinterference capability,while the system is robustness in modeling plant uncertainty.
