Method and Apparatus for Operating a Haptic System
Patent application, 2020

The present invention relates to a method for operating a haptic system, such as a vehicle electric steering system, etc. We present a real-time disturbance observer based control strategy for a desired steering feedback, ranging from virtual to realistic behavior. The invention covers both the impedance (or torque) and admittance (or position) control concepts.
