damp: Damping and Natural Frequencies for Continuous Systems

In control: A Control Systems Toolbox

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.

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.

Value

Returns the natrural frequencies and damping factors in a list:

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