H/sup /spl infin// optimization with time domain and other constraints

The fundamental H/sup /spl infin// optimization problem of control has become fairly well understood at both the qualitative and computational level. In many mature optimization theories one has a characterization of an optimizer which is a set of equations the optimizer must satisfy. Solution of these equations (say by Newton's method) then gives the optimizer. The trick is getting optimality equations which are nondegenerate with respect to Newton's method. This was done for pure H/sup /spl infin// optimization in previous papers by the authors, and in this article they extend the theory to include time domain constraints. Also an algorithm is described, a numerical example is presented, and a method for solving control problems is outlined.<>
