This paper presents the performance comparison of a conventional proportional-integral (PI) controller with a fuzzy logic controller (FLC) based tuned PI controller incorporating an adaptive hysteresis current controller for an interior permanent magnet synchronous motor (IPMSM) drive. For the proposed drive two FLCs are used. One of these is a novel Sugeno type FLC, which is used to tune the PI controller...
This paper presents a closed loop vector control of an interior permanent magnet synchronous motor (IPMSM) drive incorporating two separate fuzzy logic controllers (FLCs). The first one is a Mamdani type FLC which minimizes the developed torque ripple by varying online the hysteresis band of the PWM current controller. The second one is an FLC based tuned proportional-integral (PI) controller where...
This paper presents a fuzzy logic controller (FLC) based tuned proportional-integral (PI) controller for interior permanent magnet synchronous motor (IPMSM) drive. The PI controller serves as the primary speed controller whose gains are tuned by a novel Sugeno type FLC. Thus, the limitations of traditional PI controllers are avoided and the performance of the drive system is improved. A flux controller...

This paper proposes a new fine quick servo system that considers the saturation of voltage and current for interior permanent magnet synchronous motor (IPMSM) to achieve a stable current response to inverter voltage saturation.

At present, vector control (VC) has been widely used in the interior permanent magnet synchronous motor (IPMSM). However, for the difference between direct and quadrature inductances and the difference of control characteristics between d-q axes current loop PI regulators, the dynamic decoupling can not be achieved, which affects the torque dynamic response and the quick startup of motor. For this...
