Development of an educational interactive hardware‐in‐the‐loop missile guidance system simulator

Abstract

This paper presents a hardware‐in‐the‐loop (HIL) simulator, named HIL‐GSS, which aims to help the students of aerospace engineering learn control and missile guidance theories effectively by using interactive instrumentation. Electromechanical components and interactive panels are illustrated. Two case‐based studies are presented to show the advantages that HIL‐GSS offers to engineering education. Steady‐state tracking errors of the PID controller based on the HIL‐GSS are around zero. The final miss distance in the real‐time HIL TV guidance engagement simulation is 0.2376 m. Those results show the reliability of the proposed HIL simulator. In addition, the students' average response to survey questions is 4.22 (1–5 grade scale), which indicates that students strongly agree or agree that HIL‐GSS is an effective educational tool.

Development of a Didactic Educational Tool for Learning Fuzzy Control Systems

“…ese results coincide with those reported by Martinez et al [37], who developed a virtual tool for the design and analysis of the administration and control of the energy of photovoltaic systems in a DC microgrid, obtaining as a result that the tool allows the dynamic simulation of different control algorithms. On the other hand, Chen et al [11] in their proposal for simulator hardware in the loop used a satisfaction survey applied to the 30 students, which indicates that they totally agree that it is an effective educational tool.…”

“…e main contribution of this research is that the proposed DET focuses on learning the fundamentals, basic structure, and application of FLC with an innovative computing tool similar to those presented in [10,11], where students have at their provision of resources to carry out simulations of control systems, managing to break down barriers in the learning process such as the high cost of having access to real processes and the gap that students perceive between theoretical concepts and practice, as demonstrated in [12,13]. When making a comparison of the proposed DET with the research carried out in [20][21][22][23], the advantage that was found was that the developed DET has the visual integration of all the elements that make up an FLC, allowing for the understanding of the designers' effects of the modifications in the control system by modifying any parameter or variable that intervenes in the controller and system to be controlled.…”

“…In a study [10], the factors that influence student behavior were defined and divided into three categories: (a) the academic environment and academic resources such as laboratories, remote laboratories, conferences, and computational tools, (b) perceptions about discipline and career, and (c) experience. One of the main trends in the educational field is the development of computational tools that facilitate the improvement in the learning of engineering concepts [11]. ese tools can be remote laboratories such as those developed in [12,13], in which the problem of not having industrial processes to carry out practices in the engineering area was solved.…”
