LabVIEW traction control dynamic simulator

Abstract

The field of traction control has made significant progress in the past decade being reported many automotive applications. In this paper, based on advanced control techniques from literature, it is presented a dynamic simulator for traction control created in LabVIEW. The application was built starting with two algorithms which allow the implementation of a control system for the traction devices of an electric vehicle. In the first stage, the block diagram of the vehicle model was developed using an one wheel model which is based on the longitudinal motion equations. In the next step, this model was used to develop two control traction systems based on Maximum Transmissible Torque Estimation (MTTE) control approach and, respectively, sliding mode control. Comparing the results of these two control methods, it is possible to conclude which of them is more reliable. Incorporating all three described subsystems in a single module, a simulator with a graphical interface, easy to be used, was developed. The simulator offers the possibility to automatically save the graphical results like image files and also to generate a report in a single Excel document with the data of interest.
