Synthesis of the controller is based on a matrix approach and polynomial theory. Autonomous control is solved using compensators. The controller was verified by simulation and the real-time experiment on nonlinear laboratory model hot-air tunnel. The recursive least squares method in delta domain is used in identification part of the proposed controller.
