Robust Stabilization of Nonlinear Delay System with Unknown Disturbance via Hamiltonian Method

Utilizing the Hamilton theorem, the paper give robust control results on nonlinear system with time delay under the disturbance observer. Firstly, a Hamiltonian isovalent form of primary equation is put forward and disturbance observer. Secondly, a robust stabilization result is given by dimension extension technique. In the end, several numerical simulations are applied to test the implement of robust stable controller on account of disturbance observer. A nonlinear system with time delay on unknown disturbances is studied in this paper.
