Control system 2

What is the algebraic sum of the reference input and feedback?

• Error Signal
• Error Detector
• Controlled system
• Controlled output

Feedback control systems are referred to as closed loop systems.

• True
• False

First order system is defined as :

• Number of poles at origin
• Order of the differential equation
• Total number of poles of equation
• Total number of poles and order of equation

Stability of a system implies that :

• Small changes in the system input does not result in large change in system output
• Small changes in the system parameters does not result in large change in system output
• Small changes in the initial conditions does not result in large change in system output
• All of the above mentioned

The roots of the transfer function do not have any effect on the stability of the system.

• True
• False

Roots on the imaginary axis makes the system :

• Stable
• Unstable
• Marginally stable
• Linear
