ABSTRACT

This study proposed a general framework for adaptive delay compensation in real-time hybrid simulation(RTHS). This framework is composed of two main parts: an adaptive feedforward controller to handle variable time delay and amplitude discrepancies, and a feedback controller to enhance the robustness of compensation. In particular, the adaptive feedforward controller is determined using a discrete physical testing system (PTS) model, whose parameters are estimated using the least-squares method. Moreover, the feedback controller is introduced to reduce dependency on the PTS model of the feedforward controller. Results of virtual and actual RTHS alongside five other compensation strategies revealed the superiority of the proposed compensation method.

摘要

本研究提出了实时混合仿真（RTHS）中自适应延迟补偿的一般框架。该框架由两个主要部分组成：处理可变时间延迟和幅度差异的自适应前馈控制器，以及增强补偿鲁棒性的反馈控制器。特别地，自适应前馈控制器是使用离散物理测试系统 (PTS) 模型确定的，其参数是使用最小二乘法估计的。此外，引入反馈控制器以减少对前馈控制器的 PTS 模型的依赖。虚拟和实际 RTHS 以及其他五种补偿策略的结果揭示了所提出的补偿方法的优越性。
