damp: Damping and Natural Frequencies for Continuous Systems

Description

damp computes the natural frequency and damping for continuous systems.

Usage

damp(sys, doPrint = TRUE)

Arguments

sys

A Continuous-time system of state-space, transfer-function or zero-pole-gain model.

doPrint

If TRUE prints out the results. Default is TRUE.

Value

Returns the natrural frequencies and damping factors in a list:

omegan = Natural Frequencies (rad/s) zeta = Damping Factors

Details

A table of the eigenvalues of the matrix a, the associated damping factors, the associated natural frequency (rad/s and Hz.) is displayed by calling the function.

When the continuous system is a state-space model, the eigenvalues of the state matrix are obtained and sorted. If the system is a transfer-function, the poles of the systems are obtained and sorted. For zero-pole systems, the poles are just extracted and sorted. The sorted eigenvalues are printed to output and used to obtain the natural frequencies and damping factors.
