MEASUREMENT AND CONTROL
Group A
Measurements
Units and standards. Measurement of electric quantities such as voltage, current and power
and power factor at various frequencies.
High and low value resistance measurement. A.C. potentiometer. A.C. bridges: Owen,
Anderson al Schering. Magnetic measurements: Flux, permeability a. B H loop.
High voltage measurements: D.C, A.c. and impulse. Frequency and time interval
measurement.
Group B
Control
Open loop and closed loop control systems. Concept of linear and nonlinear systems.
Transfer functions a block diagrams. Signal flow graph.
State variables: State equations. Matrix representation of state equations. Relationship
between state equations and transfer functions.
Time response: Transient analysis of feedback systems - First and second order systems.
Steady state error and error coefficients.
