Implementing PWM Controller Using MATLAB S-Function

Resource Overview

Implementation of PWM controller utilizing MATLAB S-Function with parameter configuration and optimization techniques

Detailed Documentation

During the implementation of a PWM controller, we can utilize MATLAB's S-function. The S-function is a specialized MATLAB function type capable of processing or generating signals, making it suitable for various signal processing and control applications. To achieve more precise control, we can configure different parameters within the S-function, such as sample time and control variable rate of change. The S-function implementation typically involves defining the system's discrete states and update equations using the `mdlInitializeSizes`, `mdlInitializeSampleTimes`, and `mdlOutputs` callback functions. Parameter optimization through these configurations helps achieve better balance between control effectiveness and resource consumption during the control process. The algorithm structure allows for real-time adjustment of duty cycles and frequency parameters based on error feedback signals.
