H_∞控制理论和MATLAB工具箱应用于电力系统稳定器设计

Design of application of H_∞ control theory and MATLAB toolbox on power system stabilizer

介绍了H∞鲁棒控制理论的基本理论和方法,并以电力系统稳定器的设计为例,具体说明了MATLAB控制工具箱的使用方法.仿真表明,将所设计的H∞电力系统稳定器配合常规的PID励磁调节器使用,具有良好的动态品质和调节精度,并能抑制振荡,提高电力系统的动态稳定.

Introduces the basic theory and method of H∞ control theory, taking design of power system stabilizer as example, states the using method of MATLAB toolbox. Simulation result shows cooperating the designed stabilizer with the PID excitation regulator can get high dynamic performance and regulation percision, restrain surge, enhance the dynamic stability of power system.
