The invention discloses an intelligent control method for cable tension of a petroleum mechanical winch. A tension feedback signal is directly transmitted to a controller in real time through a tensiometer which is independently and separately arranged between a ground pulley and a roller, the controller outputs a control signal to a driving motor through a frequency converter, the driving motor transmits motion to the roller, the output torque of the driving motor is dynamically adjusted, and a full-closed-loop tension control system is established. The control method comprises the following steps: calculating a layer index of hierarchical control according to the total length of a cable and the size of a roller, optimizing an initial value of a control parameter for each layer by combining analysis modeling and prior experience, and adaptively correcting a PID (Proportion Integration Differentiation) regulation value by using fuzzy control, a neural network or a fuzzy neural network intelligent control algorithm. The method can be used for cable car tension intelligent control of the winch for petroleum drilling, well logging, well repairing and the like, the tension control precision can be improved, the labor amount of operators is reduced, and a foundation is laid for achieving an intelligent winch system.

    本发明公开了一种石油机械绞车缆绳张力智能控制方法。通过独立分离设置在地滑轮与滚筒之间张力计,直接将张力反馈信号实时传递给控制器,控制器通过变频器输出控制信号给驱动电机,驱动电机将运动传递至滚筒,动态调节驱动电机的输出转矩,建立全闭环张力控制系统。其控制方法是根据缆绳总长和滚筒尺寸计算分层控制的层指数,对每一层通过分析建模和先验经验相结合优化控制参数初值,再用模糊控制、神经网络或模糊神经网络智能控制算法对PID调节值进行自适应校正。本发明可用于石油钻井、测井、修井等绞车的缆车张力智能控制,可提高张力控制精度,减轻操作人员劳动量,为实现智能化绞车系统奠定基础。
