“…The description of "workless forces" (10) is placed on both the stator-fixed frame and the rotor-fixed frame, while the description (13) is placed on the stator-fixed frame and (14) is placed on the rotor-fixed frame. Based on the electric machinery theory, it is clear that the part (WrA(0Y2ywr4e .which is in the top two equations of mathematical model (2), figures the electromotive force in the stator circuit which is caused by the air-gap field cutting the stator windings, and (WI(Or))21gr eI which is in the bottom two equations of mathematical model (2), figures the electromotive force in the rotor circuit which is caused by the air-gap field cutting the rotor windings.…”

“…So, for the description (13), no physical interpretation can be given. Therefore, the matrices defined for the "workless forces" in the present case should be chosen as (13) or (14), and equivalent damping matrices should be defined as (15) or (16) correspondingly. The stable condition of PBC for IM is the damping coefficient K1>-R.…”

“…However, the stable condition of the PBC system for IM, viz. the region in which the equivalent damping matrix Res is uniformly positive definite, is the damping coefficient K1 must be bigger than npL2mgu 1(4Rr) [1][2][3][4][5][6][7][8][9][10][11][12][13]. So the chosen damping coefficient K1, it is a proportional coefficient in the feedback control, must increase with the rotor speed.…”

In this paper, based on the idea of passivitybased control, a new stable condition of the passivity-based controller for induction motor, which is wider than the present stable condition, is presented and proven by the different choices of the "workless forces" and state variables. The problem that a big proportional coefficient, which is required for the PBC for IM when the machine is running in high-speed region, will make the system oscillate because of the time-discrete and the restriction of system bandwidth is solved. Based on the some academic analyses, the forms of the description of the "workless forces" are given. The results of simulation and experiment validate the stable condition proposed in this paper once more.
