        摘要：This paper briefly described the characteristics of urban rail transit, such as ,the linear motor subway, monorail, new transport system, light rail transit and low-speed traffic in regular magnetic and so on, a small cross-section of linear motor subway and non-adhesion driving, monorail transportation system for the overhead lines and vehicles which used rubber tires, new traffic system with the function of self-steering systems and unmanned, low-floor light rail transport system to facilitate the train ride down to meet the traffic environment of urban areas, low-speed magnetic levitation transportation systems usually with low noise relatively. Most of them cought select large slope or the small radius curve line, and they cought also be served as the supplement of large-capacity conventional subway, which have been attached by the world’s major cities for access to satellite, science and technology parks, and large residential or tourist attractions such as branch lines. Compared with the conventional metro vehicles, the difference of its basic structure is mainly manifested in bogie structure.

        摘要：In the technology of sensorless vector control, the rotor resistance uncertainty has important influences on the accurate observation of the rotor flux and identification of the rotor speed. The rotor resistance robust observer which has rotor resistance uncertainty suppression on the speed identification is presented. According to the Lyapunov stability theory, a new Lyapunov function is setted, in theory, could ensure the stability of observer in the full speed range, then the rotor speed adaptive law is deduced. Make a comprehensive simulation comparison with the current popular resistance and the rotor speed dual identification method, the studies show that: the proposed rotor resistance robust observer method in the range of speed has a good suppression of rotor resistance uncertainty on the pace of speed identification and a high robustness, as well as its small amount calculation, simple structure, easily meets the performance of real-time, it has more advantage on the engineering application.

        摘要：At present, most of the pantograph slide images based on the image processing to detect slide wear are obtained by using overhead mode, but this way has some limitations for some complex arched. In this paper, a better way using yang-shot to capture pantograph slide images has been proposed. Firstly CCD cameras shoot the pantograph slide image, which transmit and store in the host detection by video capture card. Then process the save images , locate the edge of pantograph slide and contact wire, in order to provide the significant datas for pantograph slide wear test.
