As the Secretary-General for Linear Motor Institution of Chinese Electrotechnical Society, the author describes the research and development of linear drive technology in China. The research history, researchers and institutes, research activities and achievements in this field in China are elucidated. The author was in charge of some subjects related to the linear drive technology in a university and made some satisfactory results. Thus, the recent research subjects and some new products are introduced by the author. In addition, the author puts forward some difficult problems, such as, marketing, design, manufacture, test and material etc. and forecasts the developing tendency of linear drive technology in China.

本文在基于人工智能和知识工程的迭代参数化设计的基础上，采用改进的模拟退火算法对直线感应电动机进行优化设计。这种优化设计方法与其它优化方法相比，具有算法高效，全局最优的优点。

本文就国内外直线电机技术的探索实验、开发应用和实用商品化三个时代的历史进行了阐述，对国内外直线电机技术在物流系统、工业设备、信息与自动化系统、交通与民用、军事及其它方面的应用作了较详细介绍。

通过对直线电机驱动带式高速包刷分拣系统PID控制器的设计和应用，在为了求得更好的控制特性的情况下,提出并设计了应用于该系统的模糊控制器。文中对这两种控制器在该系统中应用的情况作了比较分析，指出了直线电机在驱动类似于这种系统的情况下，在控制精度要求更高的条件下，采用模糊控制将会更适合。
