SECTION-B
2. With a neat sketch discuss the PLC network that is used for communication of plant
parameters in a process control environment and monitoring. How the control algorithm
is developed in intelligent control?
3. Prove the Fuzzy DeMorgan law.
a) ( )
C C C C
A A A B ? ? ?
b) ( )
C C C C
A A A B ? ? ?
4. Explain how the ANN can be used for process identification with neat sketch.
5. Discuss the working of I-P converter with the help of suitable diagram.
6. A sensor provides temperature data as 360 mV/ ?C. Develop a comparator circuit that
goes high when temperature reaches 350?C.
SECTION-C
7. Explain with sketch and block diagram, a direct digital control (DDC) system used for a
chemical process.
8. Draw a circuit diagram for sample and hold circuit using an operational amplifier and
discuss its working. A Sample/Hold circuit settles to within 1 percent of its final value at
5 ?s. What is the maximum resolution and speed with which an ADC can use this data
assuming that the ADC is ideal?
9. Assuming XI, X2 & X3 to be three limit switches with normally open contact and C1, C2
& C3 be the limit switches with the normally closed contact. Form at least three-ladder
diagram to energize a coil using OR-AND circuit. How can you provide interfacing
operations?
NOTE : Disclosure of Identity by writing Mobile No. or Making of passing request on any
page of Answer Sheet will lead to UMC against the Student.
