(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.
