<p>PURPOSE:To enable inspecting easily a failure of a VVVF vehicle controller by causing said controller to simulation-operate by the use of an artificial main circuit, an artificial threephase induction motor circuit and an artificial induction motor servo controller. CONSTITUTION:The output voltage of an artificial main circuit 20 is supplied to an artificial three-phase induction motor circuit 30 composed of a reactance element x, a resistance element r1, a susceptance element b, a conductance element g, and a variable resistance element r2 corresponding to the secondary resistance of an induction motor. An artificial induction motor servo controller 34 causes a variable resistance element r2 to vary according to a pulse signal PS and a speed signal VS from a controller 11. Also, said controller 11 changes said pulse signal PS on the basis of said speed signal VS and a feedback motor current signal mi and changes also the output voltage of said artificial main circuit 20.</p> |
