ELECRONICS AND INSTRUMENTATION
SEVENTH SEMESTER

MODULE 1
Introduction to computer control of process – need for computers in control systems- functional block diagram of a computer control system- direct digital control-multi channel data acquisition system- SCADA – online hierarchical control- digital control interfacing- process input- output interface along with processing- data logger. Virtual instrumentation: definition- parts of the system- windows in data acquisition-personal computers for data acquisition system and instrument control- instrument drivers

MODULE 2
Control algorithms: design of control algorithms using Z transforms- dead beat algorithm- dahlia’s method- ringing- Kaman’s approach- digital equivalent to a conventional controller- PID algorithm- position and velocity form stunning techniques- self tuning and adaptive algorithms- stability of sampled data control system- Scurry- ohm stability criterion- replaced Z transforms to system with dead line- smith predictor
Algorithms

MODULE 3
System modeling and identification – mathematical model for process- 1st order, 2nd order process without and with pure delay- higher order systems- process modeling from step test data- pulse testing for process identification- linear lowest square algorithm

MODULE 4
Programmable logic controllers- combinational logic controllers- sequential logic controllers- logic controller design using programmable logic devices- PLC –configuration – ladder diagram-PLC programming languages- commercially available PLC’s- relay based PLC –microprocessor based PLC –interlocks- connecting PLC to computer –use of PC and PLC –case study of bottle filling system

MODULE 5
Distributed control systems- significant of DCS – configuration- data highways, field buses, multiplexers and remote terminal units of displays – CRT displays- flow sheet symbols, I/O hardware and set point stations
