In this paper, thermal characteristics of heating network are modeled on the basis of transmission delay and temperature loss pertaining to pipelines. Then, a dispatch optimization model aiming to minimize daily operation costs of the CCHP microgrid is developed, in which constraints on load balance, equipment safety and thermal characteristics are considered. The optimization is a mixed integer non-linear programming problem that can be solved by GAMS. Simulation results demonstrate that the dispatching model proposed in this paper can fully exploit thermal storage capacity of heating network and change the profile of heat load, and thereby deliver more economical and practical dispatching solution. Therefore, thermal characteristics of heating network must be taken into account when dispatching a CCHP microgrid.","PeriodicalId":6669,"journal":{"name":"2019 34rd Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"39 1","pages":"317-322"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85800232","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}

In the control design process, based on the Lyapunov function and adding a power integrator method, a control law is designed to make the nonlinear lower-triangular systems locally finite-time stability. Under the nested saturation control technique, the nonlinear lower-triangular systems is globally finite-time stabilization by adjusting the saturation. Then, according to the basic idea of optimization, the proposed control method can make the cost function be minimized by selecting the appropriate parameters in the controller, and achieves the goal of control optimality.

The DTC problem of MRRs is transformed into an optimal control issue, which consists of local namely controller, local optimal feedback controller and robust compensator. By using desired states of coupled subsystems to substitute their corresponding actual states, the strict norm-boundedness assumption of interconnections can be avoided. By using self-learning ability of neural network (NN), an identifier is constructed to approximate the subsystem dynamics. Then, the local desired control law can be obtained based on identified dynamics. A critic NN is constructed to solve Hamiltonian-Jacobi-Bellman (HJB) equation, and the local tracking feedback control policy is derived. To remove the overall error caused by the substitution, identification and approximation of critic NN, a robust term is added to guarantee the reliable performance of MRR system. The stability of the closed-loop system is ensured to be asymptotically stable by using the Lyapunov's direct methods. Finally, simulation studies show the effectiveness of the proposed scheme.","PeriodicalId":6669,"journal":{"name":"2019 34rd Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"38 1","pages":"440-445"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89214171","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}

However, the traditional charging method needs long charging time and has fixed charging position that is inflexible, which shortens the effective working time of electric vehicle. In order to solve these problems, a dynamic wireless power transfer (DWPT) system is designed in this paper. During the driving of the car, the coupling coefficient between transmitter coil and receiving coil will change dramatically. In this case, the passivity-based controller (PBC) with a DC/DC buck converter is proposed to maintain the stability of output current, thus to increase the working power and efficiency. Finally, a DWPT simulation model is established in PLECS. Simulation results demonstrate that the PBC control strategy can not only ensures the stability but also achieves fast convergence to the desired working point. Besides, the soft switching of the system has been realized.","PeriodicalId":6669,"journal":{"name":"2019 34rd Youth Academic Annual Conference of Chinese Association of Automation (YAC)","volume":"08 1","pages":"381-386"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80141525","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}
