Open and closed Loop Systems
The open and closed loop systems have been used in technology education and engineering classes for decades. Below you will find definitions of all the components of both systems, labeled diagrams, technology study game for the students, a work sheet, and quiz.
|
System: when multiple items work together to accomplish a task Open - Loop System: a system that has an Input (Desired Product), a Process (means of producing that product), and an Output (Actual Product) but does not have a method of comparing the Output to the Input Closed - Loop System: a system that has all the components of an Open - Loop System plus a means of monitoring and comparing the Output (Product) to the Input (Desired product) and making adjustments when needed. Input : Desired result or product of a system Process: The part of the system that produces the product using the 7 resources of technology (Capital, Energy, Information, Materials, People, Tool and machines, and time. Output: the actual product made by the system, it does not have to be tangible Monitor: part of the closed-loop system that evaluates the output (product) Compare & Adjust: part of the closed-loop system that compares the output (product) to the Input (desired product and making necessary changes to the process in needed. |
