Kontrola prekrmiljenja elektromagnetnega aktuatorja na podlagi meritve električnega toka med vklopom in izklopom

Žust, Peter (author), Majdič, Franc (mentor)

Cilj magistrske naloge je bil najti način za kontrolo prekrmiljenja konvencionalnega hidravličnega potnega ventila, krmiljenega z elektromagnetnimi aktuatorji, na podlagi meritve električnega toka med vklopom in izklopom elektromagnetnega aktuatorja. V okviru naloge smo predstavili metodo, ki temelji na izračunu magnetnega pretoka iz izmerjenega električnega toka. Metodo smo eksperimentalno in numerično preverili. Na podlagi izbrane metode smo izdelali napravo za kontrolo prekrmiljenja ventila. Napravo smo testirali in ugotovili, da je primerna za uporabo pri serijskem testiranju konvencionalnih potnih ventilov.

• Title: Switching control of a solenoid actuator based on electrical current measurement during power on and power off

Abstract

The aim of this master’s thesis was to find a suitable solution for the switching control of a solenoid-operated hydraulic directional control valve based on measurement of the electric current during excitation and de-excitation of the actuator. In this thesis we present a method based on the calculation of the magnetic flux from the measured electric current. The method was tested experimentally and numerically. Based on the proposed method, a device for switching control of the valve was built. The device was tested and found to be suitable for series testing of directional control valves.
