Communication

Question 1
List the advantages and the disadvantages of a closed handbuild operate on ashes.
Advantages:
Faster response to an input signal.
Effective flapping rejection.
Better tracking of reference signals.
humiliated sensitivity to schema parameter errors (example: errors in plant or biddingler gains)
Low sensitivity to changes in calibration errors (recalibration is unnecessary)
More accurate control of plant under disturbances and literal variations.
Effective and flexible control tuning by varying the control gain
use to stabilize systems that be inherently unstable in the open-loop form.
Disadvantages:
lead the use of sensors which increase the system costs.
Involve more components which leads to more costs and complexity
The power costs (due to high gains) are high.
It has a more complex design, and harder to build.
Sometimes obtaining the take amount is either hard or not economically feasible.
initial tuning is more difficult especially if the bandwidth is narrow.




There is everlastingly a steady state error ( with proportional controllers)
The system tends to become unstable as the gain is increased beyond certain limits.
Question 2
Pressure measurement transmitter
A pressure mensuration transmitter has a elongate input-output graph just like the one shown in measuring transmitter graph. The input range is 0 to 200 kilopascals (kPa), and the output range is 10 to 50 mA. Find the following:
railroad siding Cm when input C = 72 kPa.
Input C when output Cm = 13.7 mA.
Solution:
Equation for pressure measuring transmitter is Cm = 0.2C + 10.
When C = 72 kPa, Substitute C into equation: Cm = 0.2 x 72 + 10 = 24.4.
procedure equation above: Cm = 0.2C + 10
Then depute 13.7mA into Cm.
Where equation as follows:-
C = 13.7-100.2= 3.70.2= 18.5 kPaIf you want to get a full essay, order it on our website: Ordercustompaper.com
