Abstract

Abstract: To solve the problem of observing rotor flux of the induction motor, based on the mathematic model of induction motor and the theory of finite-time, the state equation of induction motor is established and the finite time observer is designed by taking the stator current and rotor flux linkage as the state parameters of the system. In addition, the observation of the flux state is realized by making the observation error converge to a given boundary in a limited time and further converge to zero. Finally, based on the linear matrix inequality(LMI)approach, the gain value of the state observer is developed, and the finite time observation of the flux is realized by computer simulation, which further verifies the validity of the proposed design method.
