Educational Project for the Teaching of Control of Electric Traction Drives

Abstract

Electric vehicles constitute a multidisciplinary subject that involves disciplines such as automotive, mechanical, electrical and control engineering. Due to this multidisciplinary technical nature, practical teaching methodologies are of special relevance. Paradoxically, in the past, the training of engineers specializing in this area has lacked the practical component represented by field tests, due to the difficulty of accessing real systems. This paper presents an educational project specifically designed for the teaching and training of engineering students with different backgrounds and experience. The teaching methodology focuses on the topology of electric traction drives and their control. It includes two stages, a simulation computer model and a scaled laboratory workbench that comprises a traction electrical drive coupled to a vehicle emulator. With this equipment, the effectiveness of different traction control strategies can be analyzed from the point of view of energy efficiency, robustness, easiness of implementation and acoustic noise.

Intrinsic Characteristics of Forward Simulation Modeling Electric Vehicle for Energy Analysis

“…Similarly, in Ref. [53], the authors model other complementary and important components, such as the converter DC/DC and inverter. After understanding the process of forward modeling, it is possible to include it in the integral simulation chain, replacing the basic components, including energy management systems, by analyzing the effect of temperature on a system's energy storage [54]; thus, it will be possible to obtain more accurate and realistic estimates.…”

Switched Reluctance Drives with Degraded Mode for Electric Vehicles

“…Figure 8 shows a schematic of the time-domain simulation model used in this work. SRDs and EVs modeling is outside the scope of this chapter, and therefore, the reader is referred to publications that deal with these aspects, such as [1,[42][43][44][45]. For convenience, the most relevant equations are included next, starting with the voltage equation for each machine phase:…”
