Convergence properties of a perturbational procedure for generating sub–optimal control laws for non–linear dynamical systems described by x=Ax+∈φ(∈,x)+ Bu are discussed. Optimization is carried out with respect to a quadratic performance index, and an estimate of the degradation of performance resulting from truncation of the perturbational solution is presented.
