This basic functionality can be used to generate these benefits for the lighting owner: • automation to reduce energy costs and improve sustainability. An IR LED is used exactly like a visible LED, you supply current with the proper polarity and limit it with a current limiting resistor. This example is extended in Figure 8.17 to include mathematical models for each of the function blocks. So by providing a feedback system, any open-loop control system can be changed into a closed loop. Then use the switch to control which device gets connected to the tv. A closed-loop control system gives a slow response in more time. The remote controls for electronic appliances use IR (Infra-Red) communication technique. The GR Peach program can be sub divided into two parts: The main Loop Program; The Timer Ticker program that run at regular intervals. Open Loop Control System and 2. If H (s) is the transfer function of the feedback path, then the transfer function of the feedback signal will be B (s) = C (s)H (s). 1.
