Abstract
This paper presents a plant-agnostic framework for cognitive AI–driven self-optimizing adaptive control of uncertain nonlinear systems with practical constraints. The method combines a stability-compatible adaptive controller with a confidence-regulated online self-optimization loop that tunes internal settings using closed-loop performance feedback under a two-time-scale design. Lyapunov-based arguments support bounded updates and practical stability. Benchmark studies with disturbances, time-varying parameters, noise, and actuator saturation show improved tracking–effort trade-offs and reduced constraint-violation risk compared with representative baselines.
