“…The general structure of an EPS usually includes a steering wheel and column, an electric motor, a gearbox, and several sensors. The electric motor can be mounted on a column, rack, or pinion (Chung and Lee, 2015). Some older vehicle models use recirculating ball and worm gear instead of rack and pinion (Chung et al ., 2020).…”

“…[6]. According to Chung and Lee, the EPS system was relatively compact, so it could be arranged in many locations, such as the EPS column, EPS rack, EPS pinion, and dual EPS pinion (see Figure 1 in reference [7]). Electric power steering systems could be combined with electronic suspension systems [8] or modern autonomous vehicle technologies [9,10].…”

EPS systems provide superior efficiency compared to conventional mechanical steering systems. Steering feel and comfort are supported by an electric motor, which is controlled by an appropriate controller. This article introduces an integrated control algorithm for EPS system control with two novel contributions. Firstly, this algorithm is synthesized based on a backstepping (BS) controller and a proportional integral derivative (PID) controller, called the BSPID controller. The control signals are amplified based on optimal coefficients determined by the loop algorithm. Secondly, a complex steering dynamics model is established based on five state variables that consider the influence of road reaction torque and other external disturbances. The performance of the control algorithm is evaluated through simulation at the MATLAB-Simulink interface. According to the numerical simulation results, the value of the steering motor and steering column angles increases when using the EPS system instead of the conventional mechanical steering system. Under the same driver torque conditions, the variation of output parameters will decrease as the speed increases based on the assisted torque map. On the contrary, the change in output parameters will increase sharply when driver torque increases (under the same speed conditions). The results obtained from the BSPID signal always closely track the reference signal in all investigated conditions with negligible errors, even though the steering system is still subject to external random disturbances. Generally, stability is guaranteed once the BSPID integrated algorithm is applied to control the EPS system.
