... of time-delay prefilters or input shapers, which cancel the zeros of the plants are presented for systems with one zero. Next, the approach is extended to systems with second order zeros. Closed form expressions are derived for first and second order zeros, and the pole-zero canceling input shapers...

... control (PMFBC) design for multiaxis motion systems is proposed in this paper. By applying stable pole-zero cancellation and including complementary zeros for uncancelled zeros for all axes, matched dynamic responses across the whole frequency range for all axes are achieved. Thus, contouring accuracy...

The robustness of the parameter adaptation is achieved by employing the recursive least-squares algorithm in combination with a dead-zone in the adaptive law. It is shown that while the controller...
