Actually, active control devices are considered as one of the most suitable chatter suppression methods for heavy duty machining operations. Generally, they are based on the generation of a reaction force over the main structure, controlled by a feedback control law, which depends on the real time vibration measurement. Several active control strategies have been proposed in the literature and due to the limited space offered by the machines for these actuators, the active control system has to be optimized, including the control law. In this work, the most employed strategies will be compared by means of a verified mechatronic model and the optimal law will be sought for each zone of stability lobes. Finally, experimental tests will be performed for verifying the results obtained by the mechatronic model simulations.
