WebClosed systems are also known as control mass systems, constant mass systems, or non-flow systems. The concept of open, closed, and isolated systems has been derived from the branch of science called thermodynamics. WebConsider an open loop control system with noise signal as shown below. The open loop transfer function due to noise signal alone is C ( s) N ( s) = G b (Equation 7) It is obtained by making the other input R ( s) equal to zero. Consider a closed loop control system with noise signal as shown below.
