Abstract: Systems and methods for controlling downhole linear motors to minimize connections to surface equipment. In one embodiment, an ESP system is coupled by a power cable to equipment at the surface of a well. The ESP system includes a linear motor and a reciprocating pump. The motor has a set of position sensors that sense the position of a mover in the motor. Combining circuitry (E.G., XOR gate) combines the outputs of the position sensors into a single composite signal in which signal components corresponding to the position sensors are indistinguishable. A single channel carries the composite signal from the ESP system to the surface equipment. A control system determines a starting position of the motor and determines its subsequent position based on transitions in the composite signal. The motor is then operated based on the position determined from the composite signal.

Abstract translation: 用于控制井下线性电机的系统和方法以最小化与地面设备的连接。 在一个实施例中，ESP系统通过电力电缆耦合到井的表面处的设备。 ESP系统包括线性马达和往复泵。 电动机具有一组位置传感器，用于感测电动机中动子的位置。 组合电路（E.G.，XOR门）将位置传感器的输出组合成单个复合信号，其中对应于位置传感器的信号分量是不可区分的。 单通道将ESP系统的复合信号传送到地面设备。 控制系统确定电动机的起始位置，并根据复合信号中的转换确定其后续位置。 然后基于从复合信号确定的位置来操作电动机。
