摘要

提出了一种基于线性二次高斯(LQG)控制器增强积分作用的鲁棒控制策略，用于隔离发电机组频率波动的鲁棒控制。在文献中，LQG已经在各个控制领域证明了它的有效性，但很少主动应用该控制方案来消除频率偏差。为了证明其有效性，将频率波动的暂态响应与自动生成控制(AGC)方案、传统比例积分导数(PID)和线性二次正则(LQR)控制器等控制方法进行了比较。

Design an Optimal LQG Control for Maintaining Nominal Frequency of a Single Area Power System

A new control strategy based on linear quadratic Gaussian (LQG) controller augmented with an integral action is introduced in this paper for the robust control of frequency fluctuation of an isolated power generating unit. In literature, LQG has proved its effectiveness in various fields of control but less initiative is taken to apply this control scheme for removing the deviation in frequency. To prove its efficacy, transient response of frequency fluctuation is compared with some of the control methods such as automatic generation control (AGC) scheme, conventional proportional-integral-derivative (PID) and linear quadratic regular (LQR) controller.
