Abstract
Control system for controlling a dynamic physical system. New, substantially decoupled axes are derived from physical axes of a dynamic system. Closed-loop controllers operate on signals representing the new or synthesized axes to control the coordinate parameters. Control signals are then converted into the original physical axes to generate signals to control the original axes. A preferred embodiment is the application of the control technique to a gantry machine having three degrees of freedom. Actual coordinates are converted to one linear coordinate and one rotational coordinate. The bandwidth of controllers operating on these two coordinates are separated so that crosstalk is diminished and performance improved.
