Systems and methods of optimized pump speed control to reduce cavitation, pulsation and load fluctuation

A method for pumping a fluid, comprising:

• providing a pumping apparatus, wherein the pumping apparatus comprises a pump, a primary mover, and a controller, wherein the controller comprises a processor and a memory device, wherein the processor is programmed to send one or more commands to the primary mover;
• actuating, by the primary mover, the pump;
• modifying at least one of the one or more commands based, at least in part, on one or more characteristics of the pumping apparatus;
• and
• sending at least one of the one or more modified commands to the primary mover to optimize at least one of the one or more characteristic of the pumping apparatus.

A method for pumping a fluid in a well operation, comprising:

• providing a pumping apparatus comprising:
• a pump, a primary mover mechanically coupled to the pump by a drive train such that the primary mover actuates the pump, a controller that sends commands to the primary mover, and a sensor coupled to the controller;
• pumping the fluid downhole;
• monitoring a first characteristic of the pumping apparatus with the sensor;
• sending a signal to the controller indicative of a magnitude of the first characteristic;
• generating a command signal to optimize a second characteristic of the pumping apparatus;
• and
• sending the command signal to the primary mover, wherein the command signal causes a speed of the primary mover to fluctuate cyclically.
