A schematic for a car cruise control is given in Figure 1(a). Complete the block diagram for this system, identifying each of the components in Figure 1(b) (see Lecture 2: Turntable). Engine Car body Electronic unit -Throttle pedal Desired Control Device speed Throttle Actuator Car body (a) (b) Figure 1: (a) Illustration of a cruise control system for a vehicle and (b) block diagram A tachometer is added to the system which measures the speed of the car. Please draw an updated block diagram for the closed loop system. What would be the advantages to using closed loop control in this application? Think of disturbances that might influence the process and discuss one of those. Modern cars are equipped with proximity sensors that measure the distance to a car ahead. Can you discuss how this could be considered in the control system.
