Described herein is a monitoring and control system for a hydraulic fracturing pump to reduce or eliminate detrimental oscillations of fluid discharge pressure caused by pump load dynamics. The monitoring and control system receives various sensor data from operation of the pump, including 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. The pump control equation or model is dedicated to the design and dynamic operation of the pump in conjunction with the number of plungers, pump dynamics, motor lag, and motor dynamics, etc. Using the pump control equation or model, the monitoring and control system determines commands to control the pump motor to reduce or eliminate the oscillating discharge pressure of the pump. 本文描述了一种用于水力压裂泵的监测和控制系统，以减少或消除由泵负载动态引起的流体排放压力的有害振荡。监测和控制系统从泵的操作接收各种传感器数据，包括泵曲柄位置，并基于泵传感器数据、泵负载数据和/或泵速度数据执行泵控制方程或模型。结合柱塞数量、泵动力学、马达滞后和马达动力学等，泵控制方程或模型专用于泵的设计和动态操作。使用泵控制方程或模型，监测和控制系统确定控制用于泵马达的命令以减少或消除泵的振荡排放压力。
