摘要
针对水下阀门永磁同步电机驱动控制负载变化频繁以及外部扰动的问题,提出一种改进的自抗扰控制(ADRC)方法,以期增强永磁同步水下阀门电机驱动控制系统在水下复杂工作情况下的抗干扰能力与稳定性。研究针对传统自抗扰理论进行改进,主要针对自抗扰理论中的扩张状态观测器(ESO)模块以及非线性状态误差反馈(NLSEF)模块进行改进,并建立了相应的基于改进自抗扰理论的永磁同步水下阀门电机驱动控制框架,并设计了针对研究用改进系统的仿真对比实验,与传统自抗扰理论电机控制模型以及无模型理论电机控制模型进行对比仿真实验。研究结果表明研究用基于改进自抗扰理论的永磁同步水下阀门电机驱动所设计的方法在速度变换过程中平均0.2 s即可达到稳定水平,同时在负载变化时具有更强的抗干扰能力。
In order to solve the problems of frequent load changes and external disturbances in the drive control of permanent magnet synchronous motor of underwater valves,an improved Active Disturbance Rejection Control(ADRC)method was proposed to enhance the anti-interference ability and stability of the permanent magnet synchronous underwater valve motor drive control system under complex underwater working conditions.In this study,the Extended State Observer(ESO)module and the Nonlinear State Error Feedback(NLSEF)module in the traditional ADR rejection theory are improved,and a permanent magnet synchronous underwater valve motor drive control framework based on the improved ADR theory is established,and simulation experiments are designed compared with the traditional ADR theory motor control model and the model-free theoretical motor control model.The results show that the average 0.2 s can reach a stable level in the process of speed conversion,and it has stronger anti-interference ability when the load changes.
