The model includes the dynamics of spool and feedback mechanism, and also covers factors such as backlash, radial leakage, overlap and dynamic friction, which make it more reasonable and perfect. Based on the model, simulation experiments were carried out to investigate the influence of backlash, radial leakage and overlap on system performance. The difference between the mechanical and electrical feedback was also explored. The results reveal that, overlap increases the steady-state error and transmission gap acts like this when no leak. The combination of backlash and valve radial leakage causes overshoots in both moving directions. The feedback mechanism increases system damping, which is helpful for restraint of speed vibration and stick-slip motion. The research supplies theoretical bases and guidelines for nonlinearities compensation control later.","PeriodicalId":356250,"journal":{"name":"2015 2nd International Conference on Information Science and Control Engineering","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123315960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the large scale PTSG problem in real-world applications, evolutionary algorithm is an attractive way to find high quality solutions. For its reliability and high performance, differential evolution algorithm (DE) has been a promising optimizer in evolutionary computing. In this paper, DE algorithm with the state-of-the-art rand/1/Either-Or mutation scheme is designed to solve PTSG problem. A simple truncating encoding method and an elaborately designed constraint effective encoding method for DE are developed. To evaluate the performance of the proposed DE algorithm, simulation experiment was conducted on a series of item banks with different scales. Superiority of the proposed constraint effective encoding method is demonstrated by comparing it with truncating encoding strategy.","PeriodicalId":356250,"journal":{"name":"2015 2nd International Conference on Information Science and Control Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131027555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The relationship between incident and transition filed can evolve from the cylindrical harmonics of one cylinder. With the iterative scattered field among cylinders each time considered as the incident field of iterative process next time, total iterative scattering matrix can be reached. With iterative curves each time analyzed, it is verified that the process of iterative among the cylinders is equivalent to the coupling process among cylinders. To test the veracity of the proposed theory, scattering of four cylinders with arbitrary radius has been calculated with both iterative T-matrix algorithm and the method of moments (MoM).
