(1)文献综述。检索九州大学计算机中心的科技文献数据库INSPEC B、C和J，收集了80篇关于逆变器驱动的高速电力列车附着控制的文献。(2)确定描述电动列车运行状态的运动方程并辨识其非线性系数。推导了高速电动列车的运动方程，在考虑自然环境的情况下，确定了其非线性系数。(3)变频驱动感应电机的三种无速度传感器矢量控制方法的研制。a)第一种是采用q轴磁通的方法，同时也提出了采用d轴磁通识别初级电阻的方法。b)第二种是采用瞬时无功功率的方法。三是应用自适应观测器定理的方法。采用电压模型对α-轴进行电流控制，大大简化了控制算法。(4)对研制的控制系统进行数值分析，并将实验结果与计算结果进行比较。用计算机对这三种异步电动机控制方法进行了分析，并利用自制的实验设备验证了它们的有效性。(5)开发附着力控制系统。将感应电机的这三种矢量控制技术应用于高速电动列车的轮轨间附着控制中，我们正在开发新的控制系统。(6)研究结果。成果发表在日本电气工程师学会学报（Transactions of Electrical Engineers in Japan） 3篇、应用电磁学与力学学会学报（Journal of Applied电磁学与力学学会）3篇、国际会议论文集（Proceedings of International Conference） 8篇等。

(1) Literature survey.Surveying Science and Technical Literature Databases INSPEC B,C and J of Computer Center of Kyusyu University, we collected 80 literatures about the adhesion control of high speed electric train driven by inverter.(2) Determination of equation of motion describing running condition of electric train and identification of nonlinear coefficients of it.Deriving the equation of motion of high speed electric train, nonlinear coefficients of it were identified being considered natural circumstance.(3) Development of three speed sensorless vector control methods of induction motor driven by inverter.a) The first one is the method that q-axis flux is used, and at same time identifying method of primary resistance is developed using d-axis flux, too.b) Second one is the method that instantaneous reactive power was used. It has a special merit that primary resistance of induction motor is robust.c) Third one is the Method that adaptive observer theorem is applied. Being considered the current control of α-axis by voltage model, control algorithm could be simplified widely.(4) Numerical analysis of developed control system and comparison of experimental results with calculated results.Analysing these three control methods of induction motor by computer, we verified their availability using the experimental equipment constructed by our stuff.(5) Development adhesion control system.Applying these three vector control techniques of induction motor to adhesion control of high speed electric train between wheels and rails, we are now developing new control system.(6) Results of study.Results so far are published in Transactions of Institute of Electrical Engineers in Japan (3 papers), Journal of the Society of Applied Electromagnetics and Mechanics (3 papers), Proceedings of International Conference (8 papers) and so on.
