To avoid the computational difficulty in solving infinite horizon optimal control problem with Riccati equation for time-varying systems, an infinite horizon dynamic optimal control method is developed using continuous time continuous state Hopfield neural networks (CTCSHNN).

Considering the super structure as elastomer, the semiactive control of sliding structure is studied by using instantaneous optimal control method.

An instantaneous optimal control algorithm for vibration contral of tall building is presentd in this paper.

A kind of nonlinear predictive control algorithm based on the hierarchical optimum strategy and dynamic optimum control method is treated as a limited horizon optimum control of a nonlinear discrete system, and the solution is obtained by the maximum principle.

It also provided a detail realization of soft control strategy and compares it with the linear optimal control strategy by simulating the system response under the condition of three phase symmetry short circuit.

And the optimal exciter is designed according to the linear optimal control theory.

In this paper, firstly based on the mathematical model of single-machine infinite bus system the state space description is built in which thyristor controlled series compensation (TCSC) is included; then according to linear optimal control theory, a TCSC controller for single-machine infinite bus system is designed by the determination of weighted matrix based on subtime optimal control.
