Following initial build, after refit or maintenance, it will usually be necessary to carry out tests of controlled systems, the control systems themselves and instruments within the control systems. The checks will usually be carried out by injecting input disturbances and watching how the output follows. Alternatively, load changes can be applied to disturb the system under control and the recovery curves observed. For example, thecontrol of diesel generators can be checked by starting large equipment such as air-conditioning plant and observing the response of the engine speed and, at the switchboard, how well the voltage control systems function. In control engineering, it is frequently concerned with the graphical representation of time-varying signals.
