Compliant Control of Electric Power Assisted Steering Systems
SAE Technical Paper Series, 2005<div class="htmlview paragraph">In this study, a compliant control strategy is developed, which makes the application of position based control strategies practicable for electric power assisted steering systems. In order to do this, an additional virtual degree of freedom is added to the system, which is stimulated by the torque exerted on the ...

Electric power assisted steering (EPAS)
IEE Colloquium on DSP Chips in Real Time Measurement and Control, 1997Concerns electric power-assisted steering (EPAS) of cars. There are more small cars than in the past, and most are front wheel drive, placing a large proportion of the weight of the car on the front wheels. This makes it desirable to fit the smaller cars with power assistance to the steering. A PAS system in smaller cars would also help maneuverability

Study on Power Control of Electric Power Steering System
ICCTP 2009, 2009The method of the proportional control power is analyzed. The oscillations of an Electric Power Steering System are found. On these bases, the improvement measures of the power control carried on a differential calculus compensate is proposed. Proportional plus differential calculus control is designed.

Electricity the Future Power for Steering Vessels
Transactions of the American Institute of Electrical Engineers, 1914Electrical development in the marine field has been confined in a large measure to the navy, and the best experience with electric steering gears has been obtained from navy installations. Up to the present time steam has been the universal power for operating steering gears, but certain disadvantages are in-herent in this system which can be overcome ...

Power boost unit for automotive electric power steering systems
5th IET International Conference on Power Electronics, Machines and Drives (PEMD 2010), 2010In recent years the use of Electric Power Steering (EPS) in small and medium-sized cars has increased as it offers significant benefits such as reduction of fuel consumption as well as increased controllability. To enable the use of EPS systems in larger vehicles, the output power has to be increased without increasing the maximum current drawn from ...

Neural controllers for electrical power steering systems
2010 IEEE International Conference on Electro/Information Technology, 2010Modern electric cars require electrical power steering systems (EPAS). Many control algorithms where employed in this field. Some of these controllers exhibit robustness and stability problems for certain road conditions. Neural networks are known for their ability to imitate systems and stay stable if operation conditions change.

Control of Electric Power Steering Systems
SAE Technical Paper Series, 1998<div class="htmlview paragraph">The dynamic characteristics of electric power steering (EPS) systems can be characterized by the transmissibility from rack load to steering wheel torque. The transmissibility can be studied by fixing the steering wheel and calculating the frequency response from the rack load to the torque needed to hold the ...

Electric Hydraulic Power Steering System Simulation Study
Applied Mechanics and Materials, 2013Properly controlling electro hydraulic power steering system can improve steering performance. The relation of motor speed, vehicle speed and steering speed is gained, according to the influence of motor speed on the steering performance. The force and angle input is set in the driver input model. Rotary valve is simulated by four orifices.

Robust Control of Electric Power Steering System
IECON 2007 - 33rd Annual Conference of the IEEE Industrial Electronics Society, 2007Electric power steering (EPS) system has been greatly developed in the last decade. Control strategy design is the core technology, which decides the man-machine interface performance of EPS. Conventional controller based on phase compensation is sensitive to the system variety and parameter uncertainty.
