Experimental evaluation demonstrates rapid speed tracking in an induction motor using prescribed sliding mode control, indicating robust performance under model uncertainties.

Key Points

To design and validate a prescribed sliding mode control technique that predetermines speed tracking convergence time and mitigates parameter variations in induction motors.
Formulated a prescribed sliding mode controller (PSMC) using Lyapunov stability theory to guarantee speed convergence within a predefined time window.
Conducted practical bench experiments on a laboratory induction motor under reference speed variations and parameter fluctuations of up to ±10%.
Compared tracking performance, convergence rate, and error against conventional adaptive sliding mode control (ASMC) and proportional-integral (PI) controllers.
The proposed PSMC decreased convergence time to 0.1 s and limited steady-state error to 0.9 rpm, outperforming conventional ASMC and PI controllers.
The controller sustained robustness against parameter variations up to ±10% with speed tracking error constrained below 2.5 rpm.
