| 针对大型风机桨叶负荷波动和变桨控制系统对位置精确控制的特殊需求,在风机的空气动力学的基础上,理论分析并计算了桨叶的变桨距载荷,并以此为依据对伺服电机选型,基于提出的模糊自适应PID控制策略,设计了电伺服变桨控制系统的位置控制器,使其满足高性能伺服系统的精确桨叶位置和快速动态响应等性能要求。在上述研究基础上,搭建了电伺服独立变桨驱动控制系统的硬件平台。实验结果不仅验证了电伺服控制策略的正确性和有效性,而且证明了所设计的电伺服独立驱动控制系统能够实现精确定位和快速跟踪,满足大型风机变桨所需的响应速度和伺服精度。 |
| 英文摘要: |
| In view of the blade load fluctuation of the large scale wind turbine and the accurate position control of the pitch control system, on the basis of the aerodynamics of the wind turbine, this paper presents a theoretical analysis and calculation of the pitch load of the blade, and on that base selects the model of the servo motor. Based on the presented fussy self-adaptive PID control strategy, it designs a position controller for the electrical pitch control system which can meet the requirement on accurate blade position and quick dynamic response of the high-performance servo system. On that base, it establishes a hardware platform for the electrical individual pitch drive control system. The experiment result not only verifies the correctness and effectiveness of the electrical control strategy, but also proves that the designed electrical individual drive control system can realize accurate positioning and quick tracking, thus meeting the requirements on the response speed and servo accuracy for the pitch of the large wind turbine. |
