DEVELOPMENT OF MATHEMATICAL MODELS FOR DESIGNING AUTOMATIC CONTROL-SYSTEM APPLIED FOR VACUUM EVAPORATOR
Main Article Content
Abstract
Designing a control system is performed with two basic steps, including an establishment of a controlling strategy and a development of programmable logic controllers. This approach can be quickly conducted based on the mathematical models which is beneficial for a reduction of designing time and cost, and an avoidance of production-equipment's damages. The present work describes a theoretical modelling method combined with an adjustment of parameters for developing controlling models of continuous vacuum-evaporation process based on the laws of conservation matter and experimental data, applied for the vacuum-evaporator comprised an internal heating element with a circulation-centre tube mounted under a flash chamber in pilot-scale. The control system using the obtained models are simulated via computational MATLAB/Simulink tools and compared with the experimental evidence. The results show that the deviation of the model is less than 10%, demonstrating that the mathematical models successfully exhibit the behavior of the actual continuous vacuum-evaporation process.
