The initial response when the output is not equal to input is called

Right Answer is:

Transient response


The transient response of a system is that part of the time response which tends to zero as tends to infinity. It is the response of the system when the input changes from one state to the other. The nature of the transient response is dependent only on the system poles and not on the type of input. The transient response of a system is also called the dynamic response. Transient response The transient response of the system is basically because of stored energy.

In a stable system, the initial response until the system reaches a steady state is called the transient response. After the transient response, the system approaches its steady-state response, which is its approximation for the commanded or desired response.

Transient response of control system means changing so, this occurs mainly after two conditions and these two conditions are

  1. Just after switching ‘on’ the system that means at the time of application of an input signal to the system.
  2. Just after any abnormal conditions. Abnormal conditions may include a sudden change in the load, short-circuiting etc.

In control system engineering, a transient response or natural response is the response of a system to a change from an equilibrium or a steady state. Due to inertia, mass, inductance, friction, and other related factors that can’t be avoided the response cannot follow the sudden change in the input therefore transient are observed.
