Abstract :
A quantitative measure of modal dominance for continuous systems is proposed. This measure takes into account both transient and steady-state information of the system. Consequently the new indices indicate which poles are dominant even when they are not the slowest. Simple formulae are developed for transfer functions and state-space models. Three numerical examples illustrate the main points of the paper
