Abstract
This paper presents a design of a cruise control based on a fractional-order proportional and integral (PI) direct torque control applied to the traction system of an electric vehicle (EV). The paper also discusses the modeling, control design and simulation, resulting in a numerical simulator composed of detailed models of the main components: transmission system, induction motor, power electronics, control system, and vehicle dynamics. The simulation was developed in MATLAB/Simulink and will allow the estimation of the energy consumption of an EV under specific configurations. Simulation results show the efficiency of the designed control. These simulations were carried out using the velocity profiles given by the New Europe Drive Cycle (NEDC).
Highlights
Among the many problems that have been considered important worldwide the two that stand out are pollution and overpopulation
In order to facilitate the implementation of fractional order derivate and integral operators, a discrete representation by Z transform could be used for the PID (20)
The direct torque control (DTC) control can be implemented through simulation, including in the system the equations of both the dynamics of the electric vehicle (EV) and the induction motors (IM)
Summary
Among the many problems that have been considered important worldwide the two that stand out are pollution and overpopulation. Different control techniques that use digital systems (as well as new power electronics devices) have evolved in the works looking for improving the performance of electric motors [2]. These electric machines have made progress in their design. Sci. 2020, 10, 364 emissions, allowing buffering and presenting a part of the solution to the problem of global warming They stand out for their high performance in the transformation of the electrical energy of the battery into the mechanical energy with which the vehicle will move (60–85%) [5].
