Abstract
A motor compensation network for use with a two-degree of freedom velocity servo controller includes first and second compensation means. The first compensation means receives a signal representing a difference between a velocity command signal and a velocity feedback signal and provides a modified output signal. The second compensation means receives the velocity feedback signal and provides a modified output signal. Bandwidth adjustment means are coupled to the first and second compensation means. Damping factor adjustment means are coupled to the second compensation means. The transfer function of the first compensation means has characteristics of an integrator. The transfer function of the second compensation means has a first and a second component. The first component has characteristics of a differentiator, while the second component has characteristics of a proportionality or a gain constant. The bandwidth adjustment means varies the gain or scale factor of the integrator of the first compensation means and the gain or scale factor of the differentiator of the second compensation means according to a predetermined relationship. The damping factor adjustment means varies th…
