| Summary: | This paper presents a novel strategy for induction motor control that combines Optimal Model
Predictive Control (OMPC) with the Super-Twisting Algorithm (STA) to enhance the performance of
field-oriented control (IFOC) strategy under disturbances and uncertainties. OMPC is exploited
for its capability to optimally handle multivariable systems with constraints, but suffers from
high computational demands, sensitivity to model inaccuracies, and limited robustness against
disturbances. To address these limitations, the proposed approach integrates STA, a second-order
sliding mode technique, which provides robustness when subjected to model mismatch and disturbances,
while reducing the chattering effect typically associated with classical sliding mode control.
By incorporating OMPC with STA into the speed and currents loops of the IFOC technique, the system
gains enhanced robustness and disturbance rejection capabilities, without increasing computational
cost making it viable for real-time applications in complex control scenarios. This synergetic
approach ensures stable and efficient performance in the face of internal variations (like
parameters variation) and external perturbations (variable references and load torque).
Simulation results demonstrate that the combined OMPC-STA strategy outperforms traditional
PI and SMC methods in terms of tracking accuracy, robustness, providing a more reliable
control solution for high-performance drives. |
