针对具有不确定干扰的汽轮发电机励磁与汽阀综合控制系统，建立鲁棒综合控制模型。运用基于 Sum of Squares(SOS） 分解技术的鲁棒控制方法(SOSRCA)，设计电力系统鲁棒综合控制方法。该方法充分考虑了综合系统中存在的不确定参数及干扰，使发电机组具有较好的鲁棒性能。控制方法的求解过程是算法化、程序化的，避免了繁琐的递归设计和参数估计过程。最后，在三机电力系统仿真中，对基于SOSRCA所得出的鲁棒综合控制律进行仿真分析与讨论，验证其有效性及优越性。

The Sum of Squares robust control approach (SOSRCA) is applied to the excitation and steam-valving coordinated control system with uncertain disturbance. The SOSRCA model of the control system is built. The control strategy fully considers the uncertain parameters and interferences existing in the control system, and the robust performance of the generator set system is good. The solution process of the control strategy is algorithmic and programmatic, which simplifies the design process and reduce the complexity of control. The simulation model test of the SOSRCA law is carried out in a three-machine power system. The result verifies its effectiveness and superiority.
