This paper presents new ideas and insights towards a novel optimal control approach for power electronic converters. The so-called stabilizing or Lyapunov-based control paradigm is adopted, which is well known in the area of energy-based control of power electronic converters, in which the control law takes a nonlinear state-feedback form parameterized by a positive scalar λ. The first contribution is the extension to an optimal Lyapunov-based control paradigm involving the specification of the optimal value for the parameter λ in a typical optimal control setting. The second contribution is the extension to more flexible optimal switchinggain control laws, where the optimal switching surfaces are parameterized by a number of positive scalars λj. Systematic derivation of gradient information to apply gradient-descent algorithms is provided. The proposed techniques are numerically evaluated using the exact switched model of a DC-DC boost converter. [ABSTRACT FROM AUTHOR] |
