If we grasp the characteristics of the unit's coordinated control system, control quality of the whole system can be improved. Furthermore, the economy and safety of power generation can be increased. Firefly algorithm is an excellent optimization algorithm and is suitable for modeling. But there exist some problems in its application such as local extreme and low optimization precision. Be aimed at these problems, random search and some new variable coefficient strategy are designed to improve original algorithm. Simulation results show that the improved firefly algorithm has better performance in optimization precision, convergence speed and ability of eliminating local extreme. The improve algorithm is used to set up a three-input-three-output coupled coordinated control system's mathematic model. Results showed that these models have excellent similarity with actual objects.","PeriodicalId":136809,"journal":{"name":"2016 2nd International Conference on Control Science and Systems Engineering (ICCSSE)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124246325","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}

PMSC output speed what is equivalent to steering pump speed should have the performance with great response agility and it has many uncertainties in the process of steering for heavy-duty vehicles. To tackle these problems, nonsingular terminal sliding mode (NTSM) control strategy combined with adaptive control was adopted. The simulation results indicate that adaptive NTSM control strategy is highly effective and accurate, and it has better anti-interference ability. The tracking performance of adaptive NTSM is greater than sliding mode control (SMC) and PID control, and the convergence rate increased by 48% than SMC.","PeriodicalId":136809,"journal":{"name":"2016 2nd International Conference on Control Science and Systems Engineering (ICCSSE)","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131740913","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}

It is assumed that Target spacecraft runs in its orbit without the ability of maneuver, while Pursuer spacecraft and Evader spacecraft have continuous maneuverability. There are opposing objectives between Pursuer spacecraft and Evader spacecraft. The objective of Pursuer spacecraft is to keep Evader spacecraft far away from Target spacecraft while Evader spacecraft tries its best to shorten the distance from it to Target spacecraft prior to being intercepted. The orbital three-player differential game terminates when Evader spacecraft performs successful interception of Target spacecraft or it is intercepted by Pursuer spacecraft. The semi-direct collocation with nonlinear programming incorporated with NSGA-II algorithm which provides the initial guess is employed to solve the current three-player differential game. Numerical simulation was provided to verify the availability of the algorithm in finding the optimal solution of the orbital three-player differential game presented in this paper, and the results show that this work will be useful to some practical applications.","PeriodicalId":136809,"journal":{"name":"2016 2nd International Conference on Control Science and Systems Engineering (ICCSSE)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123746742","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}

A potential but manageable cause of this effect is the inefficient control of traffic light timing cycle that is not proactively respond to the characteristics of the considering intersection and time-dependent condition of the traffic. In this paper, we propose a finite-interval model that finds effective green time for each of the four phases light timing in each cycle. The objective is to acquire satisficing solution, by means of Bat algorithm (BA) to minimize spoilage time at an intersection. The effectiveness of model was validated using a simulation experiment on a crowded intersection in Bangkok that has imbalanced numbers of accommodated lanes and formless urbanism. The traffic condition is simulated by the microscopic traffic simulator called `Simulation of Urban Mobility' (SUMO). The experimental result confirmed the effective improvement when compared with the traditional fix-time operational control.","PeriodicalId":136809,"journal":{"name":"2016 2nd International Conference on Control Science and Systems Engineering (ICCSSE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130806418","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}
