Anesthesia is used in surgery to induce unconsciousness. One problem with drug-induced unconsciousness is large differences in patient responsiveness. Furthermore, the patient response changes during an operation. A model of drug-induced anesthesia control is shown in Figure AP9.2. The proxy for unconsciousness is the arterial blood pressure.
(a) Plot the Bode diagram and determine the gain margin and the phase margin when T = 0.05 s. (b) Repeat gain. Determine the bandwidth of the closed-loop system.
