Marine permanent magnet synchronous propulsion motors have problems, such as low reliability and difficult maintenance in the traditional control. In this paper, a sensorless control system for motor (PMSM) based on parameter identification is proposed. According to mathematical model of two-phase rotating coordinate system, reference adaptation (MRAS) used estimate rotor speed position motor. ...

This paper introduces a sensorless nonlinear control scheme based on feedback linearization (FLC) of an open-end winding five-phase induction motor (OeW-5PIM) topology fed by dual neutral point clamped (NPC) inverter. The suggested is combined with the sliding mode (SM) controller to improve dynamic performance (i.e., rising time, overshoot, etc.) studied motor. Furthermore, stator-current-base...

This paper presents a nonlinear cascaded control design that has been developed to (1) improve the self-sensing speed performance of an interior permanent magnet synchronous motor (IPMSM) drive by reducing its and torque ripples phase current harmonic distortion (2) attain maximum while utilizing minimum current. The system consists two controls for loop. A fuzzy logic controller (FLC) is emplo...

Product information given in purchase situations influences purchase behavior. In online purchase situations, the use of recommendation agents increases the value of product information as information becomes adaptive and thus more relevant to consumers’ information needs. Correspondingly, mobile recommendation agents (MRAs) may also increase the value of product information in bricks-and-morta...
