Abstract
This paper outlines a method for using an active steering system with two electrical actuators (one power-steering actuator and one superposition actuator) in order to manipulate the steering rack position without torque feedback to the steering wheel. To this effect, the power-steering actuator is used to implement a feed-forward control in order to compensate for the inertial effect introduced by the angle superposition. A rudimentary steering system model is used to derive the relevant transfer functions and assemble the control law for the superposition actuator. Experimental results of a research project at the BMW Group are included.
