An automatic drug delivery system is used in the regulation of critical care patients suffering from cardiac failure [24]. The goal is to maintain stable 735 For the nominal time delay of T = 1 s, plot the step response and verify that steady-state tracking error and percent overshoot specifications are satisfied. Determine the maximum time delay, 7", possible with the PID controller that continues to stabilize the closedloop system. Plot the phase margin as a function of time delay up to the maximum allowed for stability. patient status within narrow bounds. Consider the use of a drug delivery system for the regulation of blood pressure by the infusion of a drug. The feedback control system is shown in Figure DP9.3. Select an appropriate gain K that maintains narrow deviation for blood pressure while achieving a good dynamic response.
