This paper described a BP Neural Network PID control method applied in the Variable Speed adjustable pitch wind turbine control system, in order to solve non-linear, parameters time changing, anti-disturb and time-lag problems, in which the pitch exactor is driven by hydraulic unit.After analyzed the hydraulic oil path, transform function modal and parameters changing at three kinds of operation states, described the BP Neural Network PID control principles, then gave the simulation result based on 7.5kW trial Variable Speed Constant Frequency wind turbine design data method, compared with regular PID control method and analyzed the changing trend. Finally the conclusion is present.

本文阐述了当前生物质材料高效燃烧利用所面对的一些主要问题，以及一种克服这些问题的燃烧方法。该方法不仅通过炉具改造来达到提高燃烧效率，而且通过把生物质材料压缩成为一带有中心燃烧通道的结构，使含灰份较多不易燃烧的稻草都可以实现高效率的燃烧。该技术可以使稻草等秸杆材料代替柴薪、煤炭用于农村和中小城镇的炊事、取暖、供热，也可以用于锅炉发电。
