摘要
为满足海底泥浆举升钻井系统对举升泵的流量和压力的稳定性以及工作范围的高要求,需保障异步电机的控制性能。在提高异步电机的动静态特性与带载能力方面,结合异步电机高阶、非线性、强耦合的多变量系统特点,设计了基于模型参考自适应(MRAS)的无传感器矢量控制海底泥浆举升泵控制系统。采用转子磁场定向的同步坐标系,实现磁通和转矩控制的完全解耦,其中磁链观测采用了带参考补偿的改进型电压磁链模型。搭建仿真与实验平台研究海底泥浆举升钻井系统电机控制的性能,实验结果表明控制系统能够满足工况要求。
In order to meet the stability of the flow and pressure of the lift pump and the high working range of the subsea mud lift drilling system,the control performance of the asynchronous motor needs to be guaranteed.In order to improve the dynamic and static characteristics and load carrying capacity of asynchronous motors,combined with the characteristics of high-order,nonlinear and strong-coupling multi-variable systems of asynchronous motors,sensorless vector control based on model reference adaptive system(MRAS)for subsea mud lift pump control system was designed.The synchronous coordinate system oriented by the rotor field was used to achieve complete decoupling of flux and torque control.The flux linkage observation used an improved voltage flux linkage model with reference compensation.The simulation and experimental platform were built to study the performance of the motor control of the seabed mud lifting drilling system.The experimental results show that the control system can meet the working conditions.
