Speed Control of a Hydraulic Motor

Article Preview

Abstract:

In this article a negative feedback Proportional Integral (PI) control of pump displacement is presented to attain desired speed of hydromotor in the loading circuit of a pedagogical open loop Hydrostatic transmission system (HST) under varying load condition. By using the state equations derived from model, a novel system inversion procedure is proposed to obtain the required pump displacement. The control strategy through system inversion is validated through bond graph model simulation.
