✦ Synopsis

Two H optimization problems of a nonlinear tracking control system: the problem of a nonlinear controller and the problem of a nonlinear plant are considered in the paper. The describing function method is used for linearization of a feedback control system. Theorems, which enable one to replace the optimization of a nonlinear system by the optimization of an approximate linear system are proven in the paper. Methods of H optimization are used to find the structure of an optimal controller of the approximate system.

This paper gives a characterization of all transfer functions that may be realized via regular static-state feedback for a SISO nonlinear control system. It is shown that the question whether there exists a feedback realizable transfer function with a given number of zeros may be reduced to a well-k

Using the optimized effective potential method in conjunction with the semianalytical approximation due to Krieger, Li, and Iafrate, we performed fully selfconsistent exact exchange-only density functional calculations for diatomic molecules with a fully numerical basis-set-free molecular code. The
