IC-351 Control Engineering [3 0 0 3]
Introductory Concepts: Plant, Systems, Servomechanism, regulating systems, disturbances, open loop control systems, closed loop control systems, linear and non-linear systems, time variant and invariant, continuous and sampled-data control systems, block diagrams, some illustrative examples.
Modeling: Formulation of equation of linear electrical, mechanical, thermal, pneumatic and hydraulic systems, electrical, mechanical analogies. Use of Laplace transforms, signal flow graphs and associated algebra, characteristics equation.
Time Domain Analysis: Typical test-input, Transient response of the first and second order systems. Time domain specification, Dominant closed loop poles of higher order systems. Steady state error and coefficients, pole-zero location and stability, Routh-Hurwitz criterion.
Root Locus Technique: The extreme points of the root loci for positive gain. Asympotes to the loci, Breakway Points, intersection with imaginary axis, location of roots with given gain and sketch of the root locus plot.
Frequency Domain Analysis: Closed loop frequency response ,Bode Plots,stability and loop transfer function. Frequency response specification, relative stability,relation between time and frequency response for second order systems. Log. Magnitude versus Phase angle plot, Nyquist criterion for stability.
Compensation: Necessity of compensation, series and parallel compensation, compensating networks, application of lag and lead-compensation.
Control Components: Error detectors-potentiometers and Synchros, Servo motors, a.c. and d.c techno generators, Magnetic amplifiers.
