In this paper we propose a model for the description of slip phenomena by using a case study based on electric triplex greens mowers. Such electric vehicles (EVs) are treated here as electromechanical systems, and their dynamics is described effectively with differential-algebraic models. We have implemented general types of nonlinear dependencies of the traction force on the slip ratiointo our models, obtained torque-speed profiles of electric vehicle performance for different surface conditions, and implemented a slip ratio control strategy.
Key words: electromechanical systems; mathematical models for automotive industry; electric vehicles; dynamics; skid prevention; differential-algebraic models; traction forces; nonlinearities; torque-speed profiles; control strategies.
