针对含STATCOM的单机无穷大系统，提出了一种鲁棒控制器设计方法。利用新近发展起来的非线性H∞理论设计了非线性系统的控制器。该方法将状态反馈精确线性化与线性H∞原理相结合，避免了求解Hamilton-Stokes by-Issacs不等式的困难。仿真结果表明，所设计的鲁棒控制器能够在较大的运行点范围内保证系统的暂态稳定性
A robust control design is presented for a single machine infinite bus system (SMIB) with a STATCOM. The controller for the nonlinear system is designed using the recently developed nonlinear H∞theory. The approach combines state feedback exact linearization with linear H∞principle, which avoids the difficulty of solving Hamilton–Jacoby–Issacs inequality. Simulation results with a number of disturbances like torque pulses and three-phase faults on the generator show that the proposed robust controller can ensure transient stability of the power system over a wide range of operating points
