Electric vehicles (EVs) constitute a very attractive solution due to environmental and technical reasons. Their reliable performance and efficiency is mainly based on applying effective control and drive techniques. Since EVs are complex electromechanical systems and their nonlinear description make the control design and analysis a cumbersome task, in this paper, sliding mode controllers (SMC) in...
Electric vehicles (EVs) are complex electromechanical systems described by nonlinear models and therefore their control design and analysis is not an easy task. In the present work, fuzzy logic controllers (FLCs) are used and examined via extensive simulations. A main weakness of the FLC approach is how to ensure system stability, and the main contribution of the paper is that a nonlinear model-based...
Induction machine (IM) is an appealing solution for many drive systems mainly due to its low cost and maintenance requirements. Since, however, the electromechanical structure of an electric vehicle (EV) is much more complex than a simple IM drive system, the design of an effective control for the entire system is a challenging issue. To this end, in this paper, the control capabilities of such an...
The nonlinear dynamic model of the complete electromechanical system of an electric vehicle is developed, in a manner that enables a rigorous stability analysis of the entire system. In particular, the model developed, includes in detail, the battery storage system, the electric machine, the power converters, used to interface the battery as well as the electric motor, and finally the dc loads. On...
The complexity of electric vehicles (EVs) as electromechanical systems make their simulation and analysis a difficult but challenging task, especially in the case studied in this paper where the EV is driven by an induction machine (IM). While IM performance is simple enough, its dynamic model introduces a variety of significant nonlinearities. Hence a main innovation of the present paper is the integration...
