ABSTRACT
The time response of a system denotes the behavior of the system over time for a given input. The time response of a control system consists of two parts: the transient response and the steady-state response. The design specifications for a control system include, among others, various parameters of the corresponding time response with respect to a given input function along with the required precision that should be preserved during the steady state. The specifications, determined in accordance to the required operation measures, represent an indicator of the system quality. Generally, certain typical input signals are selected so as to correlate the system response to a given signal and its operational behavior under canonical conditions. The most common input signals are: unit step function; ramp function; Dirac function; parabola function; and sinusoid function.
