摘要
In this paper, an active control approach with the employments of two piezoelectric actuators, the Neural Networks (NNs) as approximators and the Lyapunov-Krasovskii functional which is used to deal with the time delayed tool vibrations is investigated for suppressing the 2-dof regenerative chatter in micro-milling. A dynamic model of micro-milling process and corresponding controlled system are established. Simulations are presented to validate the control performances of developed control approach.
