Optimal design of digital anticipatory servomechanisms with good noise immunity

A frequency-domain approach to the design of digital feedback controls for SISO systems is presented. The noise gain is minimized, subject to a phase margin constraint. The controller is expressed as a repeated-pole expansion, which reduces the optimization to a quadratic problem and a linear system...

Summary:A frequency-domain approach to the design of digital feedback controls for SISO systems is presented. The noise gain is minimized, subject to a phase margin constraint. The controller is expressed as a repeated-pole expansion, which reduces the optimization to a quadratic problem and a linear system of equations. PID+filter controls are produced as a limiting case.
