• Resumen

  • The control lab module presented in this paper culminates with a hands-on experience of the basic theory given in an introductorycontrol systems course. This module, which is placed during the last two sessions of an undergraduate control laboratory course,focuses on the modelling of two DC motors with different characteristics, parameter identification, and the impact of differentmodel-order reduction techniques on control design. This module integrates theoretical, numerical and experimental analysis ofpractical relevance, and redirects students to focus more on performance measures and analysis. This paper details the objectives,equipment needed, laboratory lectures, experimental procedures, and observation and analysis desired for this module. It alsoincludes assessment results pertaining to student learning. In addition, this paper provides a novel condition for neglecting thearmature inductance. This condition, which is elaborated theoretically and verified experimentally in this paper, is shown to bemore reliable than the two conditions presented in the literature.
