Numerical techniques for the inverse optimal control problem in limited state feedback systems

The numerical problem of finding the performance index parameters {Q}, for which a given control {u = fx} is optimal, is studied. Two successful algorithms are described for the single input case. Both apply to systems which are optimal within the constraint of limited state availability. The structure of Q must be prespecified to allow only r free parameters (where r is the dimension of the feedback vector). This ensures that the solution is unique. Numerical examples and program listings are included
