论文摘要
在本文中，我们表明混合积分器增益系统（HIGS）是非线性负虚拟（NNI）系统。我们证明，线性负假想（NI）系统和HIGS的正反馈互连在渐近稳定。在单输入单输出框架中，我们将HIG应用于MEMS纳米灵敏剂，作为线性NI系统的一个示例。我们通过模拟分析了时间域和频域中闭环互连的稳定性和性能，并证明了HIG作为NNI控制器对线性NI系统的适用性。
In this paper, we show that a hybrid integrator-gain system (HIGS) is a nonlinear negative imaginary (NNI) system. We prove that the positive feedback interconnection of a linear negative imaginary (NI) system and a HIGS is asymptotically stable. We apply the HIGS to a MEMS nanopositioner, as an example of a linear NI system, in a single-input single-output framework. We analyze the stability and the performance of the closed-loop interconnection in both time and frequency domains through simulations and demonstrate the applicability of HIGS as an NNI controller to a linear NI system.
