A moving boundary model is introduced to describe the transient phenomena of evaporator, which is an important component of ORC. Based on the partial-differential equations expressing the conservation principles of mass and energy, coupled with flue gas and tube wall energy equations, a set of ordinary-differential equations can be obtained by integrating separately over the three regions: unsaturated liquid, liquid-vapor mixture, and the superheat vapor. The state space equation of evaporator can be derived by linearizing the obtained equations at the operating point. Finally, the simulation results are presented to show the feasibility of the proposed method of modeling.","PeriodicalId":114901,"journal":{"name":"Proceedings of the 10th World Congress on Intelligent Control and Automation","volume":"157 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115596776","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 fault recovery architecture is designed to call the decision algorithm and supervise the implementation of the autonomous mission based on petri net formalism, which can respond to the changes in the environment and internal issues.

External disturbances are eliminated through L2 controller. A robust controller incorporated with switching control scheme is proposed against the parameter uncertainties with guaranteed stability. Different from conventional parameter adaptive learning method, the decreasing problem of learning precision can be avoided due to the fast varying of uncertain parameters, and parameter switching law can be obtained through the Lyapunov stability theory. The proposed controller yields asymptotical convergence to the given depth for the vehicle.

Back EMF detection circuit noise and interference introduced by the PWM signal will affect the Back EMF zero-crossing detection signal, resulting in fluctuations and drift, using conventional MT solution method to extract rotor speed information can not effectively filter out interfering signals, and achieve high stability speed control. To improve speed stability control performance, accurate information to extract the rotor speed is needed as the feedback of controller. This paper designed a second-order state observer based on the speed of detection, compared with the conventional speed demodulation algorithm can effectively filter the back EMF zero-crossing signal interference, and accurately extract the rotor speed information.
