This work proposes a novel robust controller in Linear Matrix Inequality framework for a single-machine infinite bus system. The mathematical equations defining the system are highly nonlinear. The novelty of the paper is the linear control law, which is obtained without linearizing the system. Along with the nonlinearity here, another two contingencies are also taken into account—(i) uncertainties in terms of parameter variations and losses and (ii) time delay in the feedback control law. The proposed controller is expected to accommodate the parameter uncertainties and the time delay. Simulation results support the analytical findings.

单机无限总线系统的鲁棒控制：一种新颖的方法

这项工作在线性矩阵不等式框架中为单机无限总线系统提出了一种新颖的鲁棒控制器。定义系统的数学方程是高度非线性的。本文的新颖之处在于线性控制律，该律无需对系统进行线性化即可获得。除了此处的非线性之外，还考虑了另外两个意外情况-（i）参数变化和损失方面的不确定性，以及（ii）反馈控制律中的时间延迟。预期所提出的控制器将适应参数不确定性和时间延迟。仿真结果支持分析结果。
