Abstract:

One of the most important environmental and financial issues is how to dispose of and recycle old engine oil. The acidic approach, which uses acids to remove pollutants and impurities, is one of the popular methods to recycle used engine oil. The paper addresses the theoretical concepts and the practical applications of identifying the transfer function by the graphical user interface using GUI as a MATLAB toolbox. The transfer function is a pivotal key tool for control system analysis and dissection of the backbone of the control system. The paper’s novelty evaluates the control system characteristics such as rise time, peak time, and process time constant for recycling used engine oil. The methodology followed by this paper is the prediction of the control system transfer function in the Laplace domain for controlling the temperature of the process. The viscosity and density of the synthesized oil were monitored and measured. In addition, the characteristics of the control system, like settling time, rise time, and overshoot, were investigated and estimated. The results obtained are the process gain constant, kc = 0.059, and the time constant, ɽp = 13.42, based on the first-order transfer function predicted from the GUI. Moreover, the paper fills the gap in implementing control systems in this era of recycling used engine oil.
