海上平台无梁式抽油机震动自适应控制方法研究
|
摘要
在海上平台使用无梁式抽油机过程中,为了保证抽油机工作产生的振动保持在一定范围内,普遍采用振动控制算法对其进行震动参数控制。但是经过长期使用发现,传统的振动控制方法所采用的算法无法对抽油机转子磁控参数进行融合计算,导致后期振动控制参数出现偏差,控制精准度与收敛性下降的问题。针对此种问题针对性提出海上平台无梁式抽油机震动自适应控制方法研究。通过引入动态自适应弱磁控制策略与HABC融合收敛控制算法,对传统控制方法采用算法存在的缺陷进行替换修正,完善震动参数计算涵盖条件范围,提升控制精准度。最后通过仿真实验证明提出方法能够解决传统方法控制精准度差的问题。
In the process of using beam-less pumping units on offshore platforms, in order to ensure that the vibration generated by pumping units is kept within a certain range, vibration control algorithm is widely used to control the vibration parameters. However, after long-term use, it is found that the traditional vibration control method can not fuse the magnetic control parameters of the pumping unit rotor, resulting in the deviation of vibration control parameters in the later stage, and the decline of control accuracy and convergence. Aiming at this problem, an adaptive vibration control method for beam-less pumping units on offshore platforms is proposed. By introducing dynamic adaptive flux weakening control strategy and HABC convergence control algorithm, the defect of traditional control method is replaced and corrected, and the condition range of vibration parameter calculation is improved to improve the control accuracy. Finally, the simulation results show that the proposed method can solve the problem of poor control accuracy of traditional methods.
