Dynamic modeling and speed control of a level-one autonomous electric vehicle

Due to the limited resources of fossil fuels and the pollution caused by them, the use of clean fuels seems necessary. In this regard, the development of electric or hybrid vehicles has great importance. In recent years, research areas related to autonomous electric vehicles have attracted the attention of automotive researchers and industrialists. These cars have different categories in terms of capabilities, including intelligent vehicle speed control. In this paper, dynamic modeling and longitudinal speed control of a level-one autonomous electric vehicle using GT-SUITE and MATLAB are investigated. Also, the model created in GT-SUITE software is validated with the help of data obtained from open-loop experimental tests. Then, after connecting the two software, the proportional-integral controller is designed to control the longitudinal speed of the vehicle and its parameters are adjusted.  Finally, the performance of the designed controller in controlling the vehicle speed in the presence of various conditions (road slope, wind blowing, and different velocity reference inputs) is evaluated.
