Parameter sensitivity analysis is usually required to select the key parameters with high optimal goal before optimization carried out, especially for flux-switching permanent magnet (FSPM) machines where lot of design should be considered. Unlike traditional studies on parameter sensitivity, which are generally experience- or statistics-based, and time-consuming, this paper proposes a method F...

This paper investigates an improved stator flux linkage observer for sensorless permanent magnet synchronous motor (PMSM) drives using a voltage-based flux linkage model and an adaptive sliding mode variable structure. We propose a new observer design that employs an improved sliding mode reaching law to achieve better estimation accuracy. The design includes two models and two adaptive estimat...

In this paper, a new type of axial gap motor, named the “flux-modulating hybrid-field consequent pole motor (FHCM)”, is proposed. To enable flux modulation, FHCM comprises rotor iron pieces sandwiched between two stators, armature, and field poles. The poles comprise permanent magnet poles, ring windings. magnetic can be adjusted by varying current. electromagnetic performance FHCM, including a...

This paper presents estimation of d-axis and q-axis inductance of an interior permanent magnet synchronous motor (IPMSM) by using an extended Kalman filter (EKF). The EKF is widely used for control applications including the motor sensorless control and parameter estimation. The motor parameters can be changed by temperature and air-gap flux. In particular, the variation of the inductance affec...

The design preciseness, the material used in productivity plus the time are coming the most important factors in motor manufacturing. Consequently, the use of interior permanent magnet synchronous machines (IPM) in hybrid vehicle seemed to be the best demands. However, and due to the earth magnet materials increasing prices such as Dysprosium and Neodymium, automobile manufacturers have looked ...

in order to solve the problem of robustness or antidisturbance of the traditional PI speed controller in the permanent magnet synchronous motor. A fuzzy PI speed controller based on load torque feedback compensation is proposed for the permanent magnet synchronous motor. The combination of fuzzy PI control strategy and load feedback compensation method can enhance the robustness and disturbance...
