Hysteresis is a ubiquitous phenomenon arising in diverseareas of engineering. In applications, it is closely linked toenergy dissipation, and it is associated with quasi-staticmemory-dependent behavior. Many applications involverate-dependent hysteresis, which merges quasi-static hysteresiswith fully dynamic behavior, thereby yielding quasi-statichysteresis as a limiting feature of dynamic system properties. Inthe proposed research, we plan to develop differential models forrate-dependent hysteresis and use these models for nonlinearsystem identification and adaptive feedback control. The proposedresearch will simplify and extend existing hysteresis models andprovide new techniques for identification and control ofhysteresis in diverse applications.

滞后是工程各个领域中普遍存在的现象。在应用中，它与能量耗散密切相关，并且与准静态内存相关行为相关。许多应用涉及速率相关的磁滞，它将准静态磁滞与完全动态行为相结合，从而产生准静态磁滞作为动态系统属性的限制特征。在拟议的研究中，我们计划开发速率相关磁滞的微分模型，并将这些模型用于非线性系统识别和自适应反馈控制。拟议的研究将简化和扩展现有的磁滞模型，并为各种应用中磁滞的识别和控制提供新技术。
