Desenvolvimento de um sistema de controle de tração para veículo elétrico four-wheel

Abstract

This paper presents the development of a traction control system for four-wheel electric vehicles using BLDC motors. To contextualize the theme, a literature review was conducted to find possible existing solutions to the proposed problem. Initially, the mathematical modeling of the engine and steering geometry was determined to allow the design of the engine speed control system. Then, experimental tests were conducted in the laboratory to determine the parameters of the Brushless DC motor used in the prototype. The experimental platform was designed and implemented so that the proposal is applied in a practical environment. To validate the mathematical model, the PSIM® software was used, while the controller design was conducted using the MATLAB® software. In general, the simulation results validate the mathematical modeling of the proposed system and demonstrate proper closed-loop velocity tracking. Moreover, the experimental results showed the adequate speed traceability, the coordination of the control systems and the possibility of integrating the projected system into a real prototype, validating the methodological procedures.
