摘要：
A monitor and control system for a hydraulic fracturing pump is described herein to reduce or eliminate harmful oscillations in fluid discharge pressure caused by the pump load dynamics. The monitor and control system receives various sensor data from the operation of the pump, including the pump crank position, and executes a pump control equation or model based on the pump sensor data, pump load data and/or pump speed data. Pump control equations or models are specific to the design and dynamic operation of the pump, incorporating the number of plungers, pump dynamics, motor lag and motor dynamics, etc. Using the pump control equations or models, the monitor and control system determines control commands for the pump motor to reduce or eliminate the oscillatory discharge pressure at the pump.
