一种机电液系统的模糊变结构模糊控制器

车辆机械式干摩擦离合器及其执行机构具有非线性、时变、变结构特点，此类机电液系统的快速跟踪控制较困难。提出一种变结构模糊控制器，此控制器具有特征识别与处理环节，能够在线调节参数和根据系统特征状态选择合适的控制模式；此控制器带有前馈环节，可以提高系统的快速响应能力。利用此模糊变结构控制器对离合器进行斜坡和二次曲线快速跟踪控制试验，结果表明，此模糊控制器对一类非线性、时变、变结构特点的机电液系统具有一定

The Fuzzy Controller and Its Application the Clutch Control

It is known that the fast trace control of the electronical -hydaulic -mechanical system with the characteristics of non-linear, time-varving and variable structure is very difficult,such as for the control of a dry friction clutch of vehicle. The Variable-Structure -Fuzzy Control (VSFC)technique is proposed, whichincludes the feature recoguition and processing units,can regulate the parameters and select the suitable control mode based on the system identification on4ine. The PD forward unit is added to enhance its fast trace ability. And the fast control experiments for the ramp and the conic section signal are finished, the vehicle clutch control results indicated the feasibility of this kind of VSFC.
