Electric Power-Assisted Steering system (EPAS) is a new power steering technology for vehicles especially for Electric Vehicles (EV). It has been applied to displace conventional Hydraulic Power-Assisted Steering system (HPAS) due to space efficiency, environmental compatibility, and engine performance. An EPAS system is a driver-assisting feedback system designed to boost the driver input torque to the desired output torque causing the steering action to be undertaken at much lower steering efforts. In this chapter, the Particle Swarm Optimization (PSO) algorithm is implemented as a tuning mechanism for Fractional-Order PID (FOPID) controller. The aim of this controller is to track the assisted current generated by the lookup table. The results show the performance and efficiency of using the PSO algorithm for FOPID tuning.
