Abstract

With the growing demand for high efficiency, energy savings, and precise lubrication control in modern engines and hydraulic systems, traditional mechanically driven oil pumps are gradually being replaced by motor-controlled intelligent oil pumps. This study investigates the design principles, control strategies, and performance characteristics of a motor-driven intelligent oil pump system.

A dynamic model of the pump–motor–controller coupling system is established to analyze the relationship between motor speed, oil flow rate, and system pressure under varying load conditions. A closed-loop control algorithm based on PID and fuzzy adaptive compensation is developed to achieve real-time regulation of pump output. The performance of the system is evaluated through simulation and bench tests, focusing on response speed, energy efficiency, and pressure stability.

Results show that the motor-controlled intelligent oil pump can reduce energy consumption by 15–25% compared to conventional fixed-displacement pumps, while maintaining pressure fluctuation within ±2% under dynamic load transitions. The intelligent control system effectively adapts to different operating modes such as cold start, acceleration, and idle lubrication.

This research provides a theoretical basis and experimental support for the development of high-efficiency, adaptive, and electronically controlled oil supply systems for next-generation automotive and industrial applications.
