Abstract
The issue of the squirrel-cage induction motor start-up mode control is considered. Its unsatisfactory dynamic state in the direct power connection mode is remarked. The problem of the squirrel-cage induction motor start-up mode control based on the definition of its current electromagnetic state, while selecting either supply voltage amplitude or additional stator circuit resistance value as the control actions, is formulated. On the basis of the maximum principle of L.S. Pontryagin and sufficient conditions for the absolute minimum of V.F. Krotov, the necessary changes in the supply voltage amplitude and the stator circuit resistance, providing the practice-orientated electromagnetic torque ripple elimination, are established. The operation results of the induction motor simulation model demonstrating the good quality of the start-up transient by proposed methods are shown.
