SPWM Inverter-Fed Brushless Feedback Motor Speed Control System

In this paper, we discuss algorithmic implementations using MATLAB M-files for SPWM inverter-fed brushless feedback motor speed control systems. These systems employ electronic technologies to precisely regulate motor speed and output power. The implementation typically involves creating MATLAB functions that model SPWM signal generation, incorporating key techniques such as vector control and space vector modulation (SVM) algorithms to enhance motor performance and efficiency. The code structure often includes separate modules for PWM signal generation, feedback processing, and control loop implementation. We will examine various algorithmic approaches and technical implementations, including how to program vector control strategies and space vector modulation techniques in MATLAB. Additionally, we will address common challenges and their solutions, such as implementing vibration and noise reduction algorithms through proper PWM switching frequency selection and filtering techniques in the control code. Through detailed analysis of these aspects, our discussion aims to provide valuable insights for developing and optimizing SPWM inverter-fed brushless feedback motor speed control systems.
