Description

Course work in automation. ACS. ATS maintaining constant fuel viscosity in DG MAN Askania 70%

 Introduction
The aim of the course work is to study the optimal settings of the regulator ATS.
Coursework is a functional analysis of a given system of automatic control, analysis of the stability of the SAR with a known law of regulation and assessment of the quality of transients. As a source of data using the equations of the typical object of regulation and the equation elements of real regulators.
  1. Schematic diagram of the SAR.
This SAR is designed to maintain a constant fuel viscosity in the DG MAN.
One of the most common is the pneumatic regulator of indirect action "Askania-Viskoimat", installed in the fuel systems of the main engines of the Kotovsky, Novgorod, etc. ships.
