Motor Control Algorithm Implementation for BLDC and PMDC

This program implements motor control algorithms supporting both BLDC (Brushless DC) and PMDC Compatible with Altair Embed Software Modeli

Key Features

Motor Types Supported:

• BLDC (Brushless DC) motors with 6-step commutation
• PMDC (Permanent Magnet DC) motors with direct voltage control

Control Architecture:

• PID-based speed control with anti-windup protection
• Separate current control for BLDC motors
• Real-time simulation with 100μs time steps

Motor Models:

• Electrical dynamics (resistance, inductance, back-EMF)
• Mechanical dynamics (inertia, friction, load torque)
• Six-step commutation logic for BLDC motors

Code Structure Analysis

The implementation follows good practices:

• Modular function design
• Global parameter management
• Comprehensive plotting and visualization
• Export capabilities for Altair Embed integration

Potential Improvements:

1. The motor models use simplified current dynamics - could be enhanced with proper differential equation solving
2. Load torque is constant - could implement variable load profiles
3. No sensor modeling (assumes perfect feedback)
4. Could add more sophisticated control strategies (FOC, DTC)

Altair Embed Integration

The code generates:

• .mat files with simulation data
• C code structure templates for embedded implementation
• Compatible data formats for model-based design
