FEEDBACK CONTROL SYSTEMS
CERTIFICATION EVALUATION EXAMS SET
FULL QUESTIONS AND COMPLETE
SOLUTION

●● 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


●● Robot
