摘要
A new parameterization of piecewise quadratic functions is presented aimed for convex optimization of Lyapunov functions. The parameterization ensures continuity of the functions, but is also flexible enough to approximate any continuous function with arbitrary accuracy. A converse Lyapunov theorem is given, stating that all exponentially stable systems of a certain class will in principle admit a piece wise quadratic Lyapunov function to be found by the given. optimization. procedure.
