Control Systems Gallery

The Control Systems Gallery is a Python module that documents a collection of standard systems for use in the analysis and design of feedback control with a focus on state-space models.

Features

• Continuous-time and discrete-time systems
• Easy integration with the Python Control package

Links

• GitHub Page

Conventions

• Individual system definitions are stored in dictionaries as a pickle file keyed to a unique 10-digit integer system ID
  • IDs 0000000000 thru 4999999999 are reserved for continuous-time systems
  • IDs 5000000000 thru 9999999999 are reserved for discrete-time systems
• At a minimum each system must have:
  • Time type, continuous ('c') or discrete ('d')
  • Dynamics representation, state-space ('ss') or transfer function ('tf')
  • Either A, B, C, and D matrices (state-space representation) or a transfer function G (transfer function representation)
    • If C and D matrices were not specified in source materials then C and D are NoneType
• Additional parameters are stored as needed
  • Consult the source material (listed in metadata) for detailed description
• Metadata (system description, source paper, authors, notes) is stored in the dictionary if available
• Column and row vectors are treated as single-dimensional NumPy arrays

System descriptions

System descriptions are located in system_descriptions.md.

This file is automatically generated from the system definition dictionaries by running system_descriptions.py.

Dependencies

The Control Systems Gallery package requires the NumPy package.
