Reducing the time delay of input torque to the electrical motor of EPS system

Pouria Gharakhanlou

Resumen


An Electric Power Steering (EPS) system will be considered in this report. The electric power steering systems have some benefits over old and traditional hydraulic power steering systems in engine efficiency, space efficiency, and environmental compatibility. According to this system, the researchers will study an electro-hydraulic steering system. In this system, all functional components have been removed in the previous systems and have been made up of an electric motor, speed sensors, torque and electrical control unit. The simplest difference between these systems and last systems is to lower the weight of the vehicle than to the hydraulic systems. The simulation results show that the torque of the motor in the two simulation modes has the same behavior as the input torque, but this torque has a time delay compared to the input. In the vehicle's steering system, it is necessary to minimize the torque associated with the motor to reduce damage to the engine and system, which is also appropriate in simulation results, so that the wave can be ignored. Comparison of simulation results showed that the control system function is much more convenient than when the torque is acted stepwise and suddenly when the input torque is inputted to the system.
