Abstract
- The paper presents a sensorless fuzzy sliding-mode speed control (FSMC) decoupled by a vector control applied to a double-star induction motor (DSIM) using a sliding mode observer (SMO) fed by two PWM voltage source inverters. The fuzzy sliding-mode control is a hybrid control technique that links two control strategies, the sliding mode and fuzzy logic, whose sign function of the discontinuous part is replaced by a fuzzy inference system to overcome the drawbacks of the chattering phenomenon. For the control, the major problem is the need for using a mechanical sensor. Which imposes an additional cost and increases the complexity of the assembly. For this reason, we propose a sliding mode observer of a high robustness to few parametric uncertainties by providing considerable correction gains. The control + observer set is simulated by the Matlab / Simulink software and the simulation results show that its performance is robust and the chattering problem is solved. [ABSTRACT FROM AUTHOR]
