DC Motor System Identification Simulator App for Online Learning of Automatic Control System Subject

With Online Learning being essential during the COVID-19 pandemic, practical laboratories were forced to be replaced by virtual or remote alternatives. This paper proposes a Simulator App built on MATLAB environment that provides students of introductory Automatic Control System subject a simulated experimental environment to learn system and transfer function identification of DC Motor-Tachogenerator system. The features of the Simulator App are discussed, followed by design of experiments suitable to be carried out using the Simulator App. Experimental results and student feedback show that the Simulator App is a feasible virtual alternative to the physical laboratory experiments.
