Abstract

This paper presents system modeling and coupling analysis of a proportional solenoid valve (PSV) with pulsewidth modulation (PWM) control mode. The coupling analysis is adopted to reveal the internal relations among the electromagnetic, mechanical, fluid, and electrical subsystems based on the integrate proportional pressure valve mode for the PSV system. Then, a simplified and practical PWM strategy is proposed to design the PSV. The dynamic performance of each subsystem is analyzed with respect to a duty cycle set. Consequently, simulation using a commercial software is presented. It infers from the results that the valve has a fast response to the control signal and can reach a small flow area at the instantaneous moment during opening and closing operations. Finally, the analytical results of the designed PSV are validated by using experimental tests. It follows from the testing results that the established model is precise and the corresponding coupling analysis results are valuable for the performance design and optimization of PSV.
