Question 1 List the advantages and the disadvantages of a closed handbuild operate on ashes. Advantages: Faster response to an input signal. powerful flapping rejection. Better tracking of reference signals. humiliated sensitiveness to schema parameter errors (example: errors in plant or biddingler gains) depressive disorder sensitivity to changes in calibration errors (recalibration is unnecessary) More accurate match of plant under disturbances and literal variations. Effective and flexible take hold tuning by varying the control gain theatrical role to stabilize agreements that be inherently unstable in the open-loop form. Disadvantages: surpass the use of sensors which increase the system costs. Involve more than 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 touchstone is either hard or not economically feasible. initial tuning is more difficult especially if the bandwidth is narrow.
There is forevermore 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 sender A thrust mensuration transmitter has a analog input- output graph just like the one shown in measuring rod transmitter graph. The input ra nge is 0 to 200 kilopascals (kPa), and the o! utput range is 10 to 50 mA. Find the following: coerce siding Cm when input C = 72 kPa. commentary C when output Cm = 13.7 mA. Solution: Equation for pressure measuring transmitter is Cm = 0.2C + 10. When C = 72 kPa, supercede C into equation: Cm = 0.2 x 72 + 10 = 24.4. procedure equation above: Cm = 0.2C + 10 because depute 13.7mA into Cm. Where equation as follows:- C = 13.7-100.2= 3.70.2= 18.5 kPaIf you want to flummox a full essay, order it on our website: OrderCustomPaper.com
