A control system controls adaptively an operation of a vapor compression system. The control system includes a memory for storing a mapping relationship between control inputs of the vapor compression system, and a processor for executing a supervisory controller and an optimization controller. The supervisory controller controls the operation of the vapor compression system using a set of control inputs selected according to the mapping relationship. The optimization controller modifies the mapping relationship in response to the operation of the vapor compression system.

The invention provides a conference details recording system for recording various types of information presented during the course of a conference by associating the contents of the presentation with speakers and with words, phrases, etc. in the presentation together with time information so that any type of information as desired can be retrieved later by using a predetermined retrieval key. The system comprises a conference room 100, an entering and leaving control unit 200 to control entering and leaving of conference participants in the conference room, a display unit 300, an image/voice collecting unit 400, a recording unit 500, an information coordinating unit 600, a superintendence control unit 700, and a clock 800, and information of the conference recorded on the recording unit 500 is retrieved by using keywords or key phrases, etc. inputted via an input/output interface 900.

The invention relates to a fan direct-driven variable pitch system based on a digital twin and an optimum design method, and belongs to an optimum design method of a wind driven generator system. An SCADA (supervisory control and data acquisition) system and a sensor are installed in a physical solid model of the fan direct-driven variable pitch system, so that data of the generator speed, the wind speed, the power, a pitch angle, the variable pitch moment, the blade vibration, the environmental temperature and the like are collected; the data are transferred to the virtual space of the digital twin of the fan direct-driven variable pitch system by virtue of a digital twin mapping model, and the virtual space of the digital twin of the fan direct-driven variable pitch system is integratedwith multi-disciplinary, multi-physical quantity, multiscale and multi-probability simulation by updating a sensor and analyzing history data, so that the life cycle process of physical solid equipment of the corresponding fan direct-driven variable pitch system is reflected, the optimum design, production and reliable operation and maintenance of the system are completed, the problem of evaluation of the quality and manufacturability of the scheme after a traditional variable pitch system is manufactured can be solved, and the production cost is effectively reduced.
