电力系统有限时间励磁控制

利用有限时间控制方法研究多机电力系统的励磁控制问题，提出了一种新的非线性鲁棒励磁控制设计方案，该控制方案收敛速度快，对诸多不确定性因素具有强鲁棒性，并且控制器中的量均为与电网参数和结构无关的局部可测量，完全实现了分散控制，仿真结果表明，该有限时间励磁控制方案的控制效果是令人满意的。

Excitation Control of Power Systems with Finite-time Control Approach

Using the finite-time control approach, the excitation control of multi-machine systems is delt with and a new excitation control strategy, finite-time excitation control strategy, is proposed. The finite-time excitation control strategy can improve systems' behaviors in several aspects such as high-speed convergence, high accuracy and robustness for some uncertainties. It is implemented via purely local measurement and independent of the parameters of power networks. Simulations demon- strate that the finite-time excitation control strategy is more effective than some other excitation controllers.
