(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 Control Systems

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.
