(Automatic) Control methods are used whenever somequantity, such as temperature, altitude, or speed, must be
made to behave in a specified desirable way over time. For
example, control methods are used to make sure that the
temperature in your home stays within acceptable levels in
both winter and summer; airplanes maintain desired heading,
speed, and altitude and that automobile emissions meet
specifications. Control systems are decision making systems
where the decisions can be based on prediction of futurebehavior derived via models of the systems to be controlled,
and on sensor-oriented observations of the actual behavior that
are fed back. Control decisions are translated into control
actions using control actuators. Developments in sensor and
actuator technology influence control methodology, which isalso influenced by the capabilities of computational resources.

Automatic Controlis the application of control theory for
regulation of processes without direct human intervention. In
the simplest type of an automatic control loop, a controller
compares a measured value of a process with a desired set
value, and processes the resulting error signal to change someinput to the process, in such a way that the process stays at its
set point despite disturbances. This closed-loop control is an
application of negative feedback to a system. The
mathematical basis of control theory was begun in the 18th
century, and advanced rapidly in the 20th.

My Take on
Automatic Control system is a strategy(or design) to
achieve specific/desired objectives in
- regulation,
- trajectory following,
- decision making, or
- optimization.

Attendance record will be sampled randomly and will be
counted toward your grade.
Students will be expected to attend all classes.
Habitual failure to do so will result in a reduced grade. An incomplete grade will only be given when a student
misses a portion of the semester because of illness or
accident. All (I) grades must be completed within thirty
days.

The instructor will strictly follow OSUs Academic
Integrity Policy as stipulated in
http://academicintegrity.okstate.edu/
There is a video clip at
http://ra.okstate.edu/provost/academic/integrity.html
that every student (and probably every faculty member)
should watch early in their academic career. This video
very clearly defines the different types of academic
misconduct and summarizes methods to avoid these
problems. Cheating on homework, quizzes or
examinations, plagiarism and other forms of academic
dishonesty are serious offenses and will subject the
student to serious penalties.

Please drop me an email introducing yourself and anything I can
help throughout the semester, if justified.
No Stillwater campus student will be allowed to enroll this class
as an Extension student.
Please identify a proctor on your job site ASAP and inform theinstructr. He or she will be the contacting point during the exam.
You are expected to take the exam at the same time as those in
Stillwater and Tulsa. If your work prevents you from doing so,
you need to have a prior approval from Instructor.
When there is a quiz given in the lecture, you need to complete
the quiz during the time you are watching the streamlined video.
Once it is done, please have your answer sheet scanned and
saved in apdffile and email it to Instructor as an attachment.
Please use TA as much and as often as you could.
