提出了一种基于算子正性的鲁棒稳定性测试方法及相关设计方法。该测试不依赖于模态截断或结构的高阶真值模型，并且与模态数据的数值无关。稳定性判据分别应用于对象（结构）和控制器，保证了负反馈闭环时的全局稳定性。因此，设计/稳定性评估只需要在环路的低阶控制器部分进行迭代。该方法可推广到非线性系统。
A robust stability test and associated design procedure based on the positivity of operators is proposed. The test does not rely on modal truncation or high-order truth models of the structure and is independent of the numerical values of the modal data. The stability criterion is applied to the plant (structure) and the controller individually, assuring global stability when the loop is closed by negative feedback. Therefore, design/stability evaluations need only iterate on the low-order controller part of the loop. The method can be extended to nonlinear systems.
