摘　　要：为了克服大型风电叶片模具液压翻转系统的不足之处,在矢量变频-液压调速的基础上,选定合适的控制对象,采用模糊-PID复合控制器对翻转过程进行控制,建立了相应的模型并进行了仿真,依据仿真结果对翻转系统进行评价和控制器参数改进。试验结果表明,改进后翻转系统的工作状况得到了很大程度的改善。In order to improve the hydraulic turnover system of the large wind turbine deficiencies, on the basis of the speed regulation of vector frequency conversion-hydraulic, selected the appropriate control objects, the fuzzy - PID compound controller was used to control the turnover process. Then the mathematical model is set up and simulation is worked out, based on the results of simulation, the evaluating of the turnover system and improvement of the controller parameters were achieved. Experimental results show that the working condition of the ameliorated turnover system was improved greatly.
