Quiz 2 review Flashcards
Name the three main variables that PID control impacts:
Rise time
Settling Time
Percent overshoot
What is dead time?
The time delay for process variable change to be observed
What do proportional control gain increases impact?
Responsiveness of control system by reducing rise time.
(Too much gain can make system unstable)
What does the integral gain impact?
Eliminates the steady state error
What do derivative control gain increases impact?
The speed of system response by reducing settling time and percent overshoot. Also can be used to stabilize a system.
What control gain is sensitive to noise as its magnitude increases?
Derivative
What are the benefits to using a single ended input instead of a differential input?
- Less materials required (wires, sensors, etc.)
What is the downsides to using a single ended input instead of a differential input?
Single-ended inputs cannot remove noise
What value does the hexadecimal A equal in base 10?
10
What value does the hexadecimal C equal in base 10?
12
What value does the hexadecimal F equal in base 10?
15
What is the mask of 1110 to 0101
0100
What do capacitive proximity sensors detect?
Presence of dielectric material
What is a downside to a mechanical limit switch?
Material can wear out and need replacement
What do inductive proximity sensor detect?
Presence of metals
