Robust control of unsteady-state nonlinear structurally undefined objects

The robust control problem for unsteady-state nonlinear in output objects under a priori, functional, and structural uncertainty is solved. In process of system operation, the order of its mathematical model can change in unpredictable way. The solution is based on the application of a robust algorithm enabling the compensation of this class of uncertainty. The control system's efficiency is proved, and the simulation results are included.
