Closed Loop System Sensor If we assume the controller C, the plant P, and the sensor F are linear and timeinvariant (i.e., elements of their transfer function C(s), P(s), and F(s) do not depend on time), the systems above can be analyzed using the Laplace transform on the variables. This gives the following relations: Solving for Y(s) in terms of R(s) gives: 18
Closed Loop System The expression Sensor is referred to as the closed-loop transfer function of the system. The numerator is the forward (open-loop) gain from r to y, and the denominator is one plus the gain in going around the feedback loop, the so-called loop gain. If , i.e., it has a large norm with each value of s, and if , then Y(s) is approximately equal to R(s) and the output closely tracks the reference input. 19
