FEEDBACK CONTROL OF DYNAMIC SYSTEMS
CHAPTERS 1 THROUGH 10 ACTUAL TEST
PAPER QUESTIONS AND SOLUTIONS GRADED
A+
◉ Control System.
Answer: an interconnection of components forming a system
configuration that will provide a desired system response
◉ Process.
Answer: possesses an input-output relationship representing the
cause-and-effect relationship, processing an input signal to provide
an output signal variable, often with a power amplification.
◉ open loop control system.
Answer: uses a controller and an actuator to obtain the desired
response, as a system without feedback
◉ Closed-Loop Feedback Control System.
Answer: utilizes a measurement of the actual output to compare the
actual output with the desired output response
, ◉ Feedback Signal.
Answer: the measure of the output
◉ Feedback Control System.
Answer: control system that tends to maintain a prescribed
relationship of one system variable to another by comparing
functions of these variables and using the difference as a means of
control.
◉ Error.
Answer: the difference between the desired output and the actual
output
◉ Negative Feedback Control System.
Answer: control system where the output is subtracted from the
input and the difference is used as the input signal to the controller
◉ Automation.
Answer: the control of an industrial process by automatic rather
than manual means
◉ Productivity.
Answer: the ratio of physical output to physical input
