Model-in-the-Loop Development in a Vector Control of Induction Machine

Abstract

The model-based design (MBD) is increasingly used in the field of electrical machine control because of the numerous advantages it offers, such as improving product quality and reducing development time. MBD is transforming the way of working of engineers and scientists since the design tasks of the laboratory and field are moved to a simulation environment in a desktop. The control system of an electrical machine can be rapidly prototyped using a simulation environment while in parallel, the software architecture necessary for its implementation in a microcontroller or DSP can be discussed and designed. The success of these two steps guarantees a better performance of the MiL, which is where the control of the machine on a simulated plant is evaluated, with a certain level of realism. If the control requirements are minimally met, where most of the errors are solved, the automatic code generation allows performing tests with the real plant, or on a PiL or HiL scenarios. In EV/HEV automotive systems, the plant is the vehicle which is also modeled to evaluate the control of the electric machine. In this chapter, the MBD is approached according to the above steps in a MiL level in a field-oriented control for induction machines. Two induction machines will be presented, one with 5 HP of power for industrial purposes, and other with 110 HP of power for electric vehicle (EV) application or full-electric aircraft propulsion propeller, both with a three-phase VSI .
