Objectives
Introduce students to modelling, analysis and design of Linear Time Invariant (LTI) systems
CO1: Represent LTI electro-mechanical systems, as a transfer function and state space models
CO2: Obtain time response of first and second order systems
CO3: Determine steady state error performance of a given system
CO4: Use methods like Routh, root locus, Nyquist and Bode plots to analyse a system
CO5: Apply root locus and Bode plots in design of systems
CO6: Apply basic state space design methods
