CtrlSolve is a small, self-hosted control-systems helper: type a transfer function G(s), then generate key plots and response curves instantly.
It’s designed for quick sanity checks (stability, margins), lightweight design exploration, and classroom-style demonstrations without heavy tooling.
- Plots: Bode (magnitude in dB + phase), Nyquist, Nichols, pole–zero map, root locus.
- Time-domain responses: step, impulse, and ramp response curves.
- Stability summary: stable/unstable, gain margin (GM) and phase margin (PM).
- Extra details: zeros/poles list and a state-space realization (A, B, C, D).
- Accepts LaTeX-style input and automatically simplifies/expands many common expressions.
