A method for speed estimation of an induction motor is elaborated. First, the rotor speed is considered as a state variable of null dynamics. A nonlinear MIMO observation technique is applied for estimating the corresponding extended state. As a result, the scheme estimates machine variables and speed except in some singular points where the extended system is not observable; then it is necessary to implement a switching structure for the observer, letting, in the vicinity of the singular points, only the machine variables be evaluated. The Simulink simulations included demonstrate nice performance properties of the rotor flux and the speed estimates.
