In this paper a sliding-mode torque and flux control is designed for encoderless synchronous reluctance motor drive. The sliding-mode plus PI controllers are designed in the stator-flux field oriented reference frame which is able to track the mentioned reference signals with a minimum pulsations in the state condition. In addition, with these controllers a fast dynamic response is also achieve...

In this paper, a smart drive system of the induction motor (IM) is proposed and adapted for applications in electric vehicles (EVs). Objectively, EV systems are robust over wide speed torque ranges. The independent encoder (encoderless) concerned with control (TCD) indirect rotor field-oriented (IRFOC) using sliding mode observer (SMO). This arrangement monitoring techniques smartly integrated ...

Haptic rendering commonly implements virtual springs using DC motors with current amplifiers and encoder-based position feedback. In these schemes, quantization, discretization, and delays all impose performance limits. Meanwhile the amplifiers try to cancel the electrical motor dynamics, which are actually beneficial to the haptic display. We present an alternate approach that fully embraces a...

In this paper, an encoderless finite-control-set model predictive control (FCS-MPC) strategy for doubly-fed induction generators (DFIGs) based on variable-speed wind turbine systems (WTSs) is proposed. According to the FCS-MPC concept, the discrete states of the power converter are taken into account and the future converter performance is predicted for each sampling period. Subsequently, the v...
