For these races, in addition to an efficient vehicle, a competition strategy is required to define the optimal speed, with the objective of finishing the race in the shortest possible time using the energy available. Two heuristic optimization methods are implemented to solve this problem, a convergence and performance comparison of both methods is presented. A computational model of the race is developed, including energy input, consumption and storage systems. Based on this model, the different optimization methods are tested on the optimization of the World Solar Challenge 2015 race strategy under two different environmental conditions. A suitable method for solar car racing strategy is developed with the vehicle specifications taken as an independent input to permit the simulation of different solar or electric vehicles. Keywords: solar car; race strategy; energy management; heuristic optimization; genetic algorithms 1. Introduction Solar car races are well-known as universities and college competitions with the aim of of promoting alternative energies and energy efficiency.

George Bernard Shaw Acknowledgments I would like to express my appreciation to my advisor Professor Joao˜ Sequeira for his guidance and continuous support through the development of my thesis. All the positive and constructive dis- cussions that we had during these last months motivated me and pushed me into wanting to do better, investigate more and find new solutions so that both of us could feel proud of our work. Abstract This thesis addresses the design and simulation of a Decision and Control System (DCS) for a Solar Powered Train (SPT). An intelligent control approach is followed, namely by modeling the whole infrastructure as a discrete event system, represented by Petri nets (PNs), and designing a supervisory controller for the whole system. The DCS is able to manage all energy consumption devices onboard the train, namely, solar panels, batteries, sensors and computational devices, in order to ensure that the train finishes its missions successfully. The system uses previously acquired information on the topology of the line, e.g., length and slopes, locations of the intermediate stations, dynamics of the train, current solar irra- diance and weather forecasting, and passenger weight to determine boundaries on the train velocity profile.

  • Teaching Instrumentation Through Solar Car Racing
    Session 1359 Teaching Instrumentation through Solar Car Racing Michael J. Batchelder, Electrical and Computer Engineering Department Daniel F. Dolan, Mechanical Engineering Department South Dakota School of Mines and Technology Abstract Solar car racing has been a means of motivating hands-on engineering education through competition among North American higher education institutions. Sunrayce, and now Formula Sun and American Solar Challenge, have tested the abilities of engineering students over the past decade. Proper instrumentation of the vehicle is critical for testing during the vehicle design and for successful racing. As an important part of the solar car team, the instrumentation team not only learns technical skills, but also the soft skills of planning, managing, and working with others to reach a common goal. Introduction Focusing engineering education on projects and competitions is a popular approach to giving students experience with real open-ended design problems, teamwork, communication, and leadership1,2,3,4. ABET requires engineering programs to demonstrate that their graduates have fundamental knowledge and know how to apply it working in teams. Student teams participating in solar car racing develop not only technical skills, but also communication, project management, and teaming skills. The Center for Advanced Manufacturing and Production (CAMP)5,6 at the South Dakota School of Mines and Technology promotes engineering education through team-based projects. One of these team projects is the solar car competition. Sunrayce, patterned after the World Solar Challenge in Australia, has been a biennial competition among North American higher education institutions. Students design, build, and race solar powered vehicles on secondary roads over a ten day period.
