A Python lib for automatic control system analysis.

IMPORTANT

This project is quite UNSTABLE, Do Not Use in Any Serious Work!

• Support transfer function and state space models.
• Time response
  • impulse
  • step
  • ramp
  • any input
• Frequency response
  • nyquist
  • bode
• Control system analysis
  • controllability
  • observability
  • pole placement
  • Lyapunov stability

NOTICE

• Two classes, TransferFunction and StateSpace, are designed for linear time-invariant system.
• Two response methods, time response and frequency response are only support the SISO system now.

• Python 3.6+
• Numpy
• Scipy
• Sympy
• Matplotlib
• nose2 (optional for test)
• Sphinx (optional for building docs)
• sphinx-rtd-theme (optional sphinx theme)
