Course Level Assessment Questions
Course Outcome 1 (CO1): Analyse electromechanical systems by mathematical
modelling and derive their transfer functions
1. For the given electrical/ mechanical systems determine transfer function.
2. Using block diagram reduction techniques find the transfer function of the given
system.
3. Find the overall gain for the given signal flow graph using Mason’s gain equation.
Course Outcome 2 (CO2): Determine Transient and Steady State behaviour of systems
using standard test signals
1. Derive an expression for time response of a given first/ second order system to step/
ramp input.
2. Determine step, ramp and parabolic error constants for the given unity feedback
control system.
3. Obtain the steady state error of a given system when subjected to an input.
Course Outcome 3 (CO3): Determine absolute stability and relative stability of a system
1. Using Ruth Hurwitz criterion, for the given control system determine the location of
roots on S- plane and comment on the stability of the system.
2. Sketch the Root Locus for the given control system.
