Abstract

This article introduces the research on synchronous control technology of hydraulic motors using constant power speed control circuits. It discusses the development history of hydraulic transmission systems, with a focus on systems that maintain constant output power while adjusting motor speed. This study emphasizes the importance of this control method for applications such as engineering machinery that require stable power and precise speed regulation under complex working conditions. Control the hydraulic system through a PID controller to synchronize the speeds of the two motors.
