In this paper, the enhanced indirect rotor field-oriented control (IRFOC) of single-phase induction motor (SPIM) drive is proposed. Its optimal stator currents are ensured by the multi-input and multi-output H∞ stator current controller, which is designed through solving the weighted mixed sensitivity criterion by the improved loop-shaping two-Riccati formulae. Moreover, the SPIM's rotor speed is also ensured by the PID controller, which is designed from solving the mean square error criterion using the genetic algorithm. The SPIM's actual behavior is modeled by the unstructured uncertainty model where significant variations in its stator and rotor resistors are taken into accounts. Therefore, an optimal trade-off between nominal performance and robust stability should be attained by the proposed IRFOC strategy while respecting some requirements such as a good tracking dynamic of the reference stator trajectories, as well as the reference rotor speed, a good decoupling behavior of the measured stator currents, a good rejection dynamic of plant uncertainties and a good suppression dynamic of prospective sensor noises. The modeling and control framework of the SPIM drive are simulated in MATLAB®/Simulink using Simpower systems library, in which the enhanced IRFOC performances are compared with those given by the standard IRFOC based upon the hysteresis current controller.
