(1)文献综述：通过对九州大学计算中心INSPEC B、C、J科技文献数据库的调研，收集了80篇关于变频器驱动的高速电动车组粘着控制的文献。(2)描述电动车组运行状态的运动方程的确定及其非线性系数的辨识。推导出高速电动车组的运动方程，考虑自然情况下的非线性系数的辨识。(3)发展了三种逆变器驱动的感应电机无速度传感器矢量控制方法。a)第一种是利用Q轴磁链的方法，该方法采用Q轴磁链的方法同时提出了利用d轴磁链识别一次电阻的方法。b)第二种方法是瞬时无功功率法。C)采用自适应观测器原理的方法。(4)对所开发的控制系统进行了数值分析，并将实验结果与计算结果进行了比较。利用计算机对这三种感应电机控制方法进行了分析，并在自行搭建的实验装置上验证了它们的有效性。(5)粘着控制系统的开发。将这三种感应电机矢量控制技术应用于高速电动列车轮轨粘着控制中，正在开发新的控制系统。(6)研究结果发表在日本电机工程师学会会刊(3篇论文)上，《应用电磁学与力学学会学报》(3篇)、《国际会议论文集》(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.
