T1 Optimal Control of a Bundle of Trajectories with Nondifferentiable Performance Criteria JF Journal of Automation and Information Sciences JO JAI(S) YR 1999 FD 1999-01-04 VO 31 IS 1-3 SP 1 OP 10 K1 Optimal control; nondifferentiable performance criteria; trajectory bundles; acceleration and focusing systems AB Problems of optimal control of trajectory bundles with nondifferentiable performance criteria are considered. Such problems arise, for example, in optimal design of different acceleration and focusing systems, in optimization of estimates in the problems of stability and sensitivity. Necessary (and in some cases also sufficient) optimality conditions are presented and substantiated for different methods of variation of control. Numerical algorithms based on these conditions are developed and evaluated in solving particular problems.
