## Abstract The use of optimal parameter estimation for the online regulation of final etch depth in an ion milling process is described. A modelโ€based control system utilizes a 3โ€D surface evolution model to predict dynamic surface profiles and etch depth. A heterodyne laser interferometer is used

A closed-loop control system to alleviate the problems of variation in the layer thickness of a milled peat crop (crop depth) has been developed for a peat milling machine (miller). The main enabling technology behind the system, an electromechanical sensor developed to give real-time measurement of

Optimization of the performance of a closed-loop, milling depth control system for a peat milling machine was undertaken. The system was optimized using a proportional-integral-derivative (PID) controller, set at a proportional gain of 50, and derivative and integral times of 0)5 and 0)89 s, respect
