The advance in control engineering education needs well-designed studies that validate what methods and tools work best. This paper addresses the lack of empirical evidence supporting innovations in control engineering education by proposing a methodology that works at different abstraction levels. Hence, innovations' impact on students' performance can be statistically analyzed either globally or locally by examining competencies or fine-grained indicators, respectively. The article reports the application of the methodology for evaluating an interactive simulation tool, named LCSD, on 101 students at the Pontifical Catholic University of Valparaiso in Chile. According to the experimental results, LCSD is an effective free alternative to enhance the student's skills on control system analysis for our automatic control course. Also, some improvements have been identified for future LCSD versions.

“…The control equipment used in our study is responsible for controlling the inverter, loading the control vectors from the application, and applying the signals of the different techniques to be tested. This equipment consists of a microcontroller mounted on prototyping PCB, optocoupler circuit with 4n35 integrated circuits, and software for the generation and control of the PWM techniques created using Labview 2009 with the National Instrument graphic programming language widely used in a wide range of applications thanks to its versatility [13] [14][15] and a own API for the communication microcontroller-Labview [16]. The motor used in our experimental setup is a three-phase induction motor with a squirrel cage, Dahlander type, which can be used to select the number of poles, thus changing the turning speed without modifying the signal frequency.…”

This work presents a new interactive tool for the study of the quality of power supply signals generated by an inverter. The tool has interactive elements to model and implement PWM techniques in a power inverter, it allows to modify any parameter of the PWM technique during the control of the inverter, being this a great advantage to make a lot of tests in a short time. In addition, the tool allows to design offline and simulate the behavior of the load that will feed the inverter. For the realization of the tool was used the graphic programming language Labview, for the control an Atmega328-PU microcontroller and an inverter Semikron-Semitech. A total of 1438 tests were carried out on a dhalander motor in 72 hours with two PWM techniques modelled with the tool, which made it possible to study the feed signal and the motor behaviour in the whole range of possible values that the parameters defining each PWM technique could take. The tool provides a great help to the experimental study of the quality of the power supply signals generated with an inverter for the power supply signal.
