Mechatronic system for pressure control

Abstract

The mechatronic system, that has been presented in this article, is a force adjustment system through pressure control. As a practical application of this system is the adjustment of the pressing force on a technological line for manufacturing rubber carpets on a textile support. The main condition, required by the technologic process, is to maintain a constant value for the pressing force during the entire process, in order to maintain a constant thickness of the rubber carpet. The mechatronic system is formed from two sub-systems, a hydraulic actuating subsystem and an electronic driving system (servo-controller). The electric signals from the transducers are sent to the servo-controller, for processing. The servo-controller compares the signals with pre-programmed values and drives the electromagnets from the proportional directional valve. By driving the proportional directional valve, the hydraulic system is driving the hydraulic cylinder, resulting the real pressing force, required by the parameters of the technological process.
