The whole circuit is constructed from several single-behavioral training circuits connected in sequence, with the action output of one circuit serving as the cue input of the subsequent one. The single-behavioral training circuit consists of time-delay modules, a reward adjustment module, and a read/write circuit for synapse weight. This single-behavioral training circuit not only simulates basic processes in operant conditioning, but also demonstrates that the training speed continues to decrease due to reward fatigue. By introducing multiple rewards, the impact of reward fatigue can be mitigated. Chaining training is also successfully implemented for a two-step target task. Finally, this neural network circuit is applied to assembly robots, enabling them to perform grasping and installation tasks adaptively.

To overcome this limitation, this paper proposes a general design methodology for dual-resonant topologies with inherent CC and CV outputs, ensuring that two output modes and ZPA input are maintained across different MI values. The proposed methodology begins by segmenting the topology into three parts, effectively decoupling the compensation parameters from MI, with the mode conversion and resonance of each segment designed independently. The design process first establishes the two output modes, followed by the ZPA input design. To achieve ZPA input, additional parameter constraints and topology compensation are introduced. Moreover, principles for identifying feasible compensation positions and corresponding parameter calculation methods are provided, enabling systematic and efficient topology design. Finally, based on the proposed methodology, an LCCL-LCLC compensated topology is derived. Experimental validation confirms the effectiveness and practical applicability of the proposed design approach, demonstrating its potential for enhancing the performance and reliability of WPT systems.</div></div>","PeriodicalId":50844,"journal":{"name":"Aeu-International Journal of Electronics and Communications","volume":"194 ","pages":"Article 155761"},"PeriodicalIF":3.0,"publicationDate":"2025-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143611552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
