CoDyControlBench: leaderboard
Metric: Design success rate (%; Fixed-3 protocol: the model always runs three design iterations with feedback and the best successful controller counts; 132 controller-design configurations (1-6 DoF, LTI/LTV/nonlinear systems, coupling, damping, SMC- and PID-family controllers), mean of three independent runs; a design succeeds when every response channel meets the steady-state band and overshoot limits). Source: arxiv.org. Saturation forecast: Around December 2026. 6 models tracked.
