Control of Electric Power Steering System – OpenModelica Simulation

As the automotive industry is evolving, Electric Power Assisted Steering (EPAS) system presents a great step forward in comparison to classical systems. Electric assist motor is the main part of an EPAS. This paper discusses methods used for control improvement as seen through Pfeffer model. Boost curve algorithm and PID controller influence the amount of current given to the assist motor. The results have shown that additional tuning can be made using PID controller which is important when optimizing settings for various conditions.
