Transputer based milling machine control with graphical man-machine interface

A time suboptimal control concept for multidimensional continuous path controls was improved and implemented. It is based on a model-following control which generates the control quantities for each axis drive with regard to the constraints of the motor current (acceleration) and speed (velocity) in order to move a mass along a desired contour with high accuracy and at high velocity under the influence of unknown disturbances. Following errors between the reference value and the actual value of the path position are avoided. The differences between the new and the conventional control concepts are shown. The advantages a transputer network offers and how it works together with the graphical man-machine interface under Windows are discussed. The transputer network and graphical interface were exclusively developed for this application
