摘要：
During a vehicle's return-to-center control process, the steering wheel's return-to-center speed is unstable due to system changes and external interference. This study proposes a current control, return-to-center method of active disturbance rejection control (ADRC). A dynamic equation of the electric power steering (EPS) system was established in order to analyze the torques, e.g. the return-to-center and the steering wheel torque. A return-to-center current control strategy based on the steering wheel speed and resist torque was developed. A linear extended state observer (LESO) of the motor speed model was designed to observe and compensate the low-frequency disturbance caused by the changes of the pipe string damping and motor parameters in real time. The tracking differentiator (TD) was used in order to track the target current and improve the motor current characteristics. The bench and vehicle test showed that this method can accurately distinguish the steering and return-to-center states and ensure that the return-to-center speed of steering wheel is smooth and has a small residual angle of return-to-center control, without affecting the steering state. © 2020, Editorial Department of Journal of HEU.
