Robust Proportional–Integral Sliding Mode Control for Induction Motors with Input Time Delay

This paper proposes a control strategy applied to three-phase induction motor (TIM) subject parametric uncertainties, perturbations, and input time delay, whose primary objective is achieve high-performance speed–torque control. The design involves predictive sliding mode observer (P-SMO) robust proportional–integral (PISM), aimed at reducing the detrimental effects of delay perturbations. proposed strategy’s effectiveness investigated through computational simulations, carried out for different scenarios, distinctions focus on consideration in feedback signals, character observer, type controller used. presented results show superior performance PISM compared with classic PI all tested scenarios. In test scenario that considers transport (SMO) without prediction does not stabilize system, requiring application P-SMO ensure stability accurate tracking TIM speed reference.
