(1)文献调查通过九州大学计算中心的科技文献数据库INSPEC B、C、J，收集了80篇关于逆变器驱动的高速电动列车粘着控制的文献。(2)描述电动列车运行状态的运动方程的确定及其非线性系数的识别在推导高速电动列车的运动方程的基础上，考虑自然情况，对高速电动列车的非线性系数进行了识别。(3)研究了三种逆变器驱动的异步电机无速度传感器矢量控制方法：a）利用q轴磁链的方法，同时提出了利用d轴磁链辨识原边电阻的方法; B）利用瞬时无功功率的方法。感应电动机的原边电阻具有鲁棒性的特点。三是应用自适应观测器原理的方法。通过电压模型考虑α轴的电流控制，可以大大简化控制算法。(4)对所研制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，对这三种控制方法进行了计算机分析，并利用自行研制的实验装置验证了它们的有效性。(5)粘着控制系统的研制将感应电动机的三种矢量控制技术应用于高速电动列车的轮轨粘着控制中，正在研制新的控制系统。(6)研究结果发表在日本电气工程师学会会刊（3篇）、应用电磁学与力学学会会刊（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.
