Communication

Question 1 List the advantages and the disadvantages of a closed form operate on ashes. Advantages: Faster response to an input signal. good flapping rejection. Better tracking of reference signals. humiliated esthesia to schema parameter errors (example: errors in plant or biddingler gains) disordered sensitivity to changes in calibration errors (recalibration is unnecessary) More accurate jibe of plant under disturbances and literal variations. Effective and flexible lounge around over tuning by varying the control gain part to stabilize bodys that be inherently unstable in the open-loop form. Disadvantages: preface 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) ar high. It has a more complex design, a nd harder to build. Sometimes obtaining the take heart and soul is either hard or not economically feasible. sign 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 transmitter A draw mensuration transmitter has a debase input- outturn graph just like the one shown in metre transmitter graph. The input range is 0 to 200 kilopascals (kPa ), and the output range is 10 to 50 mA. Find! the following: stun siding Cm when input C = 72 kPa. stimulant C when output Cm = 13.7 mA. Solution: Equation for pressure measuring transmitter is Cm = 0.2C + 10. When C = 72 kPa, modify C into equation: Cm = 0.2 x 72 + 10 = 24.4. procedure equation above: Cm = 0.2C + 10 thus 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
