Brushless DC Motor Sliding Mode Variable Structure Control Program - Using Variable Speed PVC Strategy

This program is designed to achieve precise control of brushless DC motors by implementing a sliding mode variable structure control strategy. The control algorithm maintains stable speed regulation under varying load and voltage conditions through robust sliding surface design and adaptive switching control. The program incorporates a variable speed PWM voltage control (PVC) strategy, which dynamically adjusts the PWM signal duty cycle to regulate output voltage, thereby enabling finer motor speed control. Key implementation features include real-time duty cycle calculation based on speed error feedback, anti-chattering techniques for smooth operation, and Hall sensor integration for rotor position detection. This control program can be widely applied in brushless DC motor control applications and provides strong technical support for related research fields.
