Abstract

In this paper, a novel low-cost digital controller to drive a buck converter fed voltage source inverter (VSI) based brushless DC (BLDC) machine has been proposed. This controller is designed to be implemented solely in digital platforms and has multiple numbers of predefined discrete duty ratios. In conjunction with buck converter fed VSI, the controller is beneficial to enhance the speed and resultant torque profile of BLDC motor drive as compared to conventional bang-bang or on-off controller. The controller also incorporates a current limiter to avoid the over-current loading of the motor. The sampling time and the design of the current limiter are mathematically derived in the paper. The working efficiency of the developed controller for the BLDC motor drive has been examined for various vital and steady-state conditions. The speed ripples, settling time, tolerance to the commanded speed, and load variations are validated and presented in this paper. The proposed controller has been performed and implemented in the field-programmable gate array platform and compared to generic pre-existing controllers to validate the cost-effectiveness of the controller.

基于Buck变换器的无刷直流电机驱动的低成本控制体系

本文提出了一种新型的低成本数字控制器，用于驱动基于降压变换器的电压源逆变器（VSI）无刷直流电机。该控制器被设计为仅在数字平台中实现，并且具有多个预定的离散占空比。与传统的bang-bang或on-off控制器相比，与降压转换器馈送的VSI相结合，该控制器有利于提高BLDC电机驱动的速度和合成转矩分布。控制器还包括一个电流限制器，以避免电机的过电流负载。本文从数学上推导了采样时间和限流器的设计。研究了所开发的无刷直流电机驱动控制器在各种关键和稳态条件下的工作效率。本文验证并给出了速度脉动、沉降时间、指令速度公差和负载变化。所提出的控制器已经在现场可编程门阵列平台中执行和实现，并与通用的预先存在的控制器进行了比较，以验证控制器的成本效益。

期刊介绍： "International Journal of Engineering Research in Africa" is a peer-reviewed journal which is devoted to the publication of original scientific articles on research and development of engineering systems carried out in Africa and worldwide. We publish stand-alone papers by individual authors. The articles should be related to theoretical research or be based on practical study. Articles which are not from Africa should have the potential of contributing to its progress and development.
