Active Return-to-Center Control Based on Torque and Angle Sensors for Electric Power Steering Systems

This paper presents a complete control strategy of the active return-to-center (RTC) control for electric power steering (EPS) systems. We first establish the mathematical model of the EPS system and analyze the source and influence of the self-aligning torque (SAT). Second, based on the feedback signals of steering column torque and steering wheel angle, we give the trigger conditions of a sta...

Voltage Control of Three Phase Inverters by Using Active Disturbance Rejection Control

Control of three phase inverters has been an important issue in recent years. This paper proposes active disturbance rejection control (ADRC) scheme for controlling three phase inverters. The main advantage of ADRC that motivated us for using this controller for inverter is that it is model independent.  This controller is used in a double loop structure including an inner current loop and oute...

On Torque Control of Vehicle Handling and Steering Feel for Avoidance Maneuver with Electric Power Steering

This paper evaluates EPS control strategies for improving vehicle handling and steering feel during high speed avoidance maneuver. Theoretical analysis of frequency response of steering angle and vehicle lateral acceleration relative to steering torque input is performed. Closed-loop simulation studies are also conducted by adopting a driver model to describe the human steering behavior. Based ...

Improved Linear Active Disturbance Rejection Control for Microgrid Frequency Regulation

The frequency regulation has become one of the major subjects in microgrid power system due to the complexity structure of microgrid. In order to solve this problem, this paper proposes an improved linear active disturbance rejection control algorithm (ILADRC) that can significantly improve system performances through changing feedback control law to reduce the disturbance estimation error of e...
