Feedback Compensation Using Derivative Signals II - Mitrovic's Method

The basic Mitrovic equations are extended to apply to variations in any chosen coefficients of the characteristic equation, thus permitting analysis of the effect of adjusting several derivative signals. Simple relationships are developed to analyze the possibility of stabilizing fourth-, fifth-, and sixth-order systems with selected feedback signals. Design procedures are given, which control the damping and frequency of the dominant roots (within available limits) by simultaneous adjustment of two derivative signals.
