Open- loop, Closed Loop & Systems Thinking
What is an Open-Loop System?
An open-loop system is a control system that has no means for
comparing the output
what is technological systems
we often use the word system. We talk of our digestive system or the fuel system of a car
what is a complex system
A complex system is a system whose properties are not fully explained by an understanding
of
its component parts
what is optomization
Optimization is a process or
methodology of designing or
making a product
criteria includes?
the design is supposed to
do, related to function, aesthetics, efficiency, etc.
Knowledge of systemsx
is a path to a better understanding of how mother
nature and human nature work.
what are the four parts of technological systems
inputs, processes, outputs, and feedback
whats an example
If a traffic light fails
at a major intersection it can
snarl traffic and cause all
kinds of problems for
motorist.
what is optimization used for
Optimization is used for a specific
design purpose to enhance or to
make small gains in desirable
characteristics.
what are some elements of aesthetics?
vision, hearing, tocuh, taste, smell
WHAT IS A SYSTEM?
A system is a group of interrelated
components designed collectively to achieve
a desired goal. Systems can be open-loop or
closed-loop.
what are the 9 core technologies
mechanical technology, electrical technology, electronic technology, structural technology, fluid technology, optical technology, thermal technology, biotechnology, and materials technology
is electricity vital True or false
true
what is trade off
Trade-off involves a choice or exchange
for one quality over another.
Constraints almost involve
1. Time
2. Budget
3. Safety among other constraints
What is an Closed-Loop System?
A closed-loop system is a control system that uses feedback from the output (the results of the
operation of any system) to control the input (something put into a system, such as resources, in
order to achieve a result).
what is a social system?
a social system is defined as a set of interrelated units that are ingaged in joint problem solving to acomplish common goals.
what happens when you flip a switch
you are
connecting to a huge
complex system
what is quality control
Quality control is a planned
process to ensure that a
product, service, or system
meets established criteria.
Designers must compare what?
the solution to the criteria and
constraints of the problem.
A system often includes a
component
why is the social system complex
because these systems are composed of individual humans
what do electric power lines do?
Electric power lines transport electricity at low costs across great distances by
taking advantage of the ability to transform the voltage using power transformers
is optimization perfect for designing true or false
true
Identifying criteria and
specifying constraints
will provide what?
the basis
for what the design
should be and what its
limits are.
