This paper presents a detailed analysis and comparative investigation for the torque control techniques of interior permanent magnet synchronous motor (IPMSM) for electric vehicles (EVs). The study involves the field-oriented control (FOC), direct torque control (DTC), and model predictive direct torque control (MPDTC) techniques. The control aims to achieve vehicle requirements that involve maximum torque per ampere (MTPA), minimum torque ripples, maximum efficiency, fast dynamics, and wide speed range. The MTPA is achieved by the direct calculation of reference flux-linkage as a function of commanded torque. The calculation of reference flux-linkage is done online by the solution of a quartic equation. Therefore, it is a more practical solution compared to look-up table methods that depend on machine parameters and require extensive offline calculations in advance. For realistic results, the IPMSM model is built considering iron losses. Besides, the IGBTs and diodes losses (conduction and switching losses) in power inverter are modeled and calculated to estimate properly total system efficiency. In addition, a bidirectional dc-dc boost converter is connected to the battery to improve the overall drive performance and achieve higher efﬁciency values. Also, instead of the conventional PI controller which suffers from parameter variation, the control scheme includes an adaptive fuzzy logic controller (FLC) to provide better speed tracking performance. It also provides a better robustness against disturbance and uncertainties. Finally, a series of simulation results with detailed analysis are executed for a 60 kW IPMSM. The electric vehicle (EV) parameters are equivalent to Nissan Leaf 2018 electric car.

“…To enable easy model parametrisation and development, while still ensuring high fidelity, behavioural modelling was used to develop the components of the power electronics library. The work was based on concepts presented in the literature (Denz, Schmitt, & Andres, 2014;Cellier, Clauß, & Urquía, 2007;Lai, Hill, & Suchato, 2019;Urkizu, et al, 2019), where the response of the system is an amalgamation of the static response and an estimation of the losses, either using analytical solutions, measurement data or the dynamic model of the system. Given the dependence of the device response on the temperature, the developed models were enhanced to capture that behaviour and thermal models for the devices were developed in accordance with (AG, 2020).…”

In this paper, a Modelica library of electrified powertrain components is presented and its applications discussed. This library is used to construct digital twins of electrified powertrains during product development. These digital twins provide value by reducing development time and cost, while once the product is in-service, they enable improved condition monitoring. The library includes a multi-fidelity and multi-scale battery and power electronics sub-library, an Electrical Drive Unit (EDU) sub-library modelling different types of electrical machines, and an electrified propulsion system sub-library of template models that leverage the battery, power electronics and EDU components found in the other sublibraries. Finally, an example of applying the proposed library to electrified vehicle development is presented.
