Khalil, Islam Shoukry Mohammed and Sabanovic, Asif (2010) Sensorless action-reaction-based residual vibration suppression for multi-degree-of-freedom flexible systems. In: The 36th Annual Conference of the IEEE Industrial Electronics Society, Phoenix, AZ, USA (Accepted/In Press)
This paper demonstrates the feasibility of controlling motion and vibration of a class of flexible systems with inaccessible or unknown outputs through measurements taken from their actuators which are used as single platforms for measurements, whereas flexible dynamical systems are kept free from any attached sensors. Based on the action reaction law of dynamics, the well-known disturbance observer is used to determine the incident reaction forces from these dynamical systems on the interface planes with their actuators. Reaction forces are considered as feedback-like signals that can be used as alternatives to the inaccessible system outputs. The sensorless action reaction based motion and vibration control technique is implemented on a flexible system with finite modes and all results are verified experimentally.
