摘要：
A differential-algebraic method is used to estimate the rotor time constant T-R of an induction motor without measurements of the rotor speed/position. The method consists of solving for the roots of a polynomial equation in T-R whose coefficients depend only on the stator currents, stator voltages, and their derivatives. Experimental results are presented.
