Open and Closed Loop Systems




Conclusion questions:
1. Describe an open loop system that has not already been given as an example. Could the system benefit from feedback? Justify your answer.


A microwave, because the appliance has a program that starts and stops at the time given to it. This system could benefit from feedback becasue if the system has something like a heat sensor, then the microwave oven will be able to sence when the object has heated up to a certain degree of temperature.

2. Describe a closed loop system that has not already been given as an example. Describe the feedback utilized, and describe why that type of feedback is utilized.

A light sensor. The feedback utilized for the light sensor is that it turns on when motion is detected, and when there is no motion for a while then it turns off. The reason why the type of feedback is utilized is to save money for keeping the lights on, helps to conserve power, and for the convenience of the people that are in the room at the moment.
