智能调整型模糊控制器的研究

Research on the Intelligent Adjustment Fuzzy Controller

在分析了不同的量化、比例因子对系统控制特性影响的基础上，提出了一种量化、比例因子智能调整式模糊控制器（ＩＡＦＣ）的算法．其中的上级模糊智能调整器能够根据系统的响应在线调整下级模糊控制器中的偏差、偏差变化率的量化因子和控制量的比例因子，下级模糊控制器利用这些因子并结合常规查表模糊控制算法完成对系统的实时控制．数字仿真结果表明，这种控制器具有良好的动静特性与鲁棒性．

In this paper,based on the analyst3 of influences on the control performance due to various factors,an algorithm of quantizing and scaling factors Intelligent Adjustment Fuzzy Controller(IAFC)is presented.The senior fuzzy ntelligent regulator in the IAFC,according to the response of the system,can adjust the quantizing factors of error and error's change and the scaling factors of the actuating signal in the junior fuzzy controller on--line,while the latter peforms the real-time with these factors and conventional fuzzy control table.The dynamic and steady quality and robustness of IAFC system is satisfied,which has been verified by the digital simulation results.
