نویسندگان
چکیده
In this paper a fuzzy logic based intelligent Extended Kalman filter (EKF) is used for the estimation of speed, rotor position ,direct and quadrature axis current of permanent magnet synchronous motor thereby eliminating the problem of design and tuning of process covariance matrix in EKF algorithm. Unlike in the previous approaches the present work uses only the sensed line currents as measurements, and thus following a blind system identification approach. A fuzzy logic control technique is utilized for control purpose. The results show the improvement in convergence of EKF algorithm when intelligent technique is introduced in it.

This paper suggests novel sensorless speed estimation for an induction motor (IM) based on a stator current model reference adaptive system (IS-MRAS) scheme. The IS-MRAS scheme uses the error between the reference and estimated stator current vectors and the rotor speed. Observing rotor flux and the speed estimating using the conventional MRAS technique is confronted with certain problems relat...

متن کاملAdaptive and intelligent control of permanent magnet synchronous motor (PMSM) using a combination of fuzzy logic and gray wolf algorithm under fault condition
Nowadays, permanent magnet synchronous motors have been widely used in industry due to the elimination of excitation losses, longer life and higher efficiency. Errors in engine and drive systems are unavoidable during operation. Therefore, a suitable scenario should be considered for when these systems fail. If the necessary predictions and control algorithms are not considered for the error co...
