A Priori Integral Persistent Excitation in Conservative Polynomial ODEs with Higher-Order Interactions

The paper proposes an approach for verifying integral persistent excitation, which is important in problems of parameter identification and adaptive control in nonlinear dynamical systems.

The approach works for conservative polynomial ODEs a priori without knowledge of the parameters.

Rigorous proofs of the corresponding theorems are provided.

An example of a nonlinear dynamical system with higher-order interactions and the application of the proposed method to it are analyzed.

The proof of the main result is formalized in the Lean formal verification language.
