Course Outcomes (COs):
CO1: Apply Lie Brackets and the Frobenius theorem to analyze system dynamics and determine conditions for system integrability.

CO2: Implement Feedback Linearization techniques to transform nonlinear systems into a canonical form suitable for control design.

CO3: Define sliding surfaces and apply them to design robust control laws that ensure system trajectories remain on the sliding surface.

CO4: Integrate concepts from nonlinear control, feedback linearization, and sliding mode control to solve practical control problems.
