A new method for the adaptive control of machining operations is presented. The proposed controller is of the self-tuning regulator type consisting of two functional blocks. The first block is a new recursive estimator offering good accuracy at a low computational cost and is used for the on-line identification of the machining dynamics. A Fast Kalman version of the algorithm that further reduces its computational complexity is also presented. The second block contains the control algorithm design which is based on the arbitrary placement of the closed-loop poles so that necessary stability and response specifications can be met. The performance of the proposed controller under noisy conditions and suddenly changing machining characteristics is finally evaluated through numerical simulations.
