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.

In this article,we introduce the idea of using Lie series to give an approximation of the optimal tra- jectory of a nonlinear optimal control problem by a discrete process.

First, the nonlinear optimal control algorithm was applied to plan the reference trajectories of automatic lane changes.

The present paper presents the optimal linewise control problem of the system governed by the mixed problem for elliptic partial differential equations from the osmotic control problem for the basis of concrete dams.
