Abstract
En 中文
• Recasts IRC tuning as explicit stability-budget allocation. • Derives tight gain-product law linking damping and tracking. • Provides NI-consistent leaky-integrator stability interpretation. • Introduces convex LMI-equivalent feasibility for IRC synthesis. • Experimental results validate bandwidth-oriented IRC design.
