Fuzzy Adaptive

In this work, design, development and analysis of a closed loop-based control strategy of a fuzzy adaptive controlled PWM operated Permanent Magnet Synchronous Motor drive has been established. The entire structure of the proposed closed loop model is made up of two loop control formation, outer loop speed and inner loop current. Therefore, to enhance the dynamic operation of the drive system classical PI controller is taken as current controller and fuzzy adaptive controller with simplified fuzzy rules have been utilized as speed controller. With the implementation of sinusoidal PWM control strategy, it is evident that the nature of armature current would be nearly sinusoidal and generated torque ripples will be lesser. The detailed dynamic performance of a permanent magnet synchronous motor drive is carried out in MATLAB/SIMULINK environment. An economic as well as efficient inverter configuration is also proposed in this article. The simulations results confirm the effectiveness of the proposed approach. The outcome of the proposed concept can be utilized for dynamic performance prediction of a light electric vehicle in a modern energy efficient environment

Flux Weakening

In order to expand the speed range for an indirect matrix converter–surface mounted permanent magnet synchronous motor drive (IMC-SPMSM), a wide speed range operation control strategy based on a flux-weakening control and an over-modulation method is proposed in this paper. In the stage of the inverter, an IMC over-modulation method is designed, which increases the fundamental voltage transmission ratio (VTR) to 1. In addition, considering the variation of the voltage limit boundary of the IMC with motor speed, flux-weakening control is implemented based on the voltage error feedback method, which maximizes the voltage utilization rate by setting the endpoint of the output voltage vector on the voltage boundary during the flux-weakening operation. In the stage of the rectifier, over-modulation is automatically switched on or off according to operation requirements by a modulation depth controller. Finally, experimental results show that the proposed strategy increases the maximum speed of the IMC-SPMSM by nearly 35% compared to the maximum torque per ampere (MTPA) method. Besides, the enlarged voltage margin by the rectifier stage over-modulation effectively shortens the setting time.
