| 摘 要： | 通过离散化输油管道瞬变流动控制方程,基于扩展Kalman滤波方法,用带有未知时变噪声统计的虚拟噪声补偿线性化模型误差,构造了鲁棒自适应Kalman滤波器,以进出口压力及站间测量点为系统的输入与输出向量,对输油管道进行状态估计,并将状态估计结果与实际运行采集数据进行对比.结果表明,该滤波器迭代收敛速度较快,其误差控制在3%以内.

| Abstract: | The control equations of transient flow on oil pipeline were discretization.Based on extended Kalman filtering method,a robust adaptive Kalman filter was designed with fictitious noise having uncertain time variant noise statistic,which could compensate linearization model errors.The input vector of the distributed parameter system(DPS) includes pressures at inlet and outlet of pipeline,and the output vector is the middle point of pipeline,so that the pressures and flow rates of pipe sections were estimated... |
