PD controller design for a system of a valve controlled hydromotor

Abstract

PD controller design methodology based on D-decomposition is considered in this paper. The method consists in tuning two parameters of a controller: proportional (P) and differential (D). The method was applied to a hydromotor controlled by a valve according to the position of the valve's piston. The results obtained in this paper show the good performance of the automatic control system in comparison with other methods of controller design and other controllers designed with the same method on the valve controlled hydromotor system.

Robust H-Infinity Tracking Control for a Valve-Controlled Hydraulic Motor System with Uncertain Parameters in the Complex Load Environment

“…Dubonjić [9] studied a PD controller design method based on decomposition, which is controlled by adjusting the proportional and differential parameters of the valve-controlled motor system, but this method does not take into account the non-linear characteristics and disturbance effects of the model. Duan, Hu, Wang et al [10][11][12] studied auto-disturbance rejection control technology, which can estimate and compensate the disturbances in real time, which improves the disturbance suppression ability of the valve-controlled motor.…”
