What is it about?
This paper presents four different control design strategies for linear quadratic regulators applied to DC-DC boost converters operating under large load range, pointing out advantages and drawbacks by means of a performance comparison.

Why is it important?
Two of the strategies are based on single controllers and the other two use a set of local controllers to cope with the entire load range.
Perspectives
The robust stability of the closed-loop linearized system with the four control strategies is investigated via the existence of a common Lyapunov function, obtained in a fast and efficient way by the solution of linear matrix inequality conditions.
