Problem 51: (25 points) Figure 5 is an example of a feedback control system that is designed to regulate the angular position θ(t) of a motor shaft to a desired value θr(t). The signal e(t) represents the error between the measured shaft angle θ(t) and the desired shaft angle θ (t). The Laplace transforms ofa,(t), θ(t), and e(t) are denoted as ΘR(s), θ(s), and E(s), respectively. The control gains Ki and K2 are chosen by the control engineer to achieve...

Problem 4 (30%) The system given in the diagram shows a typical control system where the system that represents the process to be controlled is called Gp(s), the controller itself is Gc(s) and the measurement system is H(s). The signals in the diagram are the input (desired repsonse) R(s), the output to be controlled Y(s), the system distrubance T(s) and the measurement noise N(s). Let's assume that the transfer function for the measurement is H(s)1 and that a good approx...
