Introduction

The SystemStructure provides a flexible framework for defining the physical structure of airborne wind energy (AWE) systems using discrete mass-spring-damper models. This structure can represent many different AWE system configurations, from simple single-line kites to complex multi-wing systems with intricate bridle networks.

The SystemStructure serves as input to the SymbolicAWEModel, which is based on ModelingToolkit and automatically generates symbolic differential algebraic equations from the structural definition.

Workflow

1. Define system components (Point, Segment, Group, etc.)
2. Assemble into a SystemStructure
3. Pass to SymbolicAWEModel for automatic MTK model generation
4. Simulate the resulting symbolic model
