continuous time systems – Solution of state and output equation – controllability and
observability - Pole Placement – State observer Design of Control Systems with
observers.

of linearising non-linear systems - Concept of phase portraits – Singular points – Limit
cycles – Construction of phase portraits – Phase plane analysis of linear and non-linear
systems – Isocline method.
