Polyphase permanent magnet synchronous motors (PMSM) model outstanding performance in comparison to three phase permanent magnet synchronous motors and this is possible because of the recent development in power electronics. Five phase permanent magnet synchronous motors have significant applications in aerospace and electric vehicles where highly accurate speed and torque control of the motor are a major requirement. This paper presents a detailed analysis of vector controlled five phase permanent magnet synchronous motors in terms of efficiency, power, speed and torque ripple analysis along with the power factor analysis at different speeds. The average torque, torque ripple, speed, speed ripple and power factor for same are calculated and analyzed. The analysis has been carried out through MATLAB Simulink Power Graphical User Interface.

This paper highlights the study and implementation of various types of Fuzzy structures using rule based interfaces for steady state and transient analysis with Hardware in Loop validation. A mathematical modeling of Type III DFIG based modified wind turbine is designed to develop maximum efficiency during faults. The modified wind turbine is controlled by various controller s illustrated in this chapter. The Mode 1 and Mode 2 are basic controllers rather the mode 3 and mode 4 are proposed controllers using derivative and integral control to active power with PI and Fuzzy logic to reactive power. This control enhance the transient stability of the wind d turbine system. The active and reactive power can be controlled and faster response can be achieved under fault conditions. All the mode results are discussed and a comparison with proposed technique is highlighted in this work. The model is designed using MATLAB simulink and the case studies are explained by taking different wind speeds and fault conditions. The model is validated using TYPHOON hardware in Loop Real Time software to get comparative results. [ABSTRACT FROM AUTHOR]
