چکیده
This research deals to introduce a new method for generalizing the well-famed Quantitative Feedback Theory (QFT) in granting robustness of Feedback linearization on nonlinear systems. In this new scheme, first applying feedback linearization, with selecting operating points in domain of system parameter's variations, nonlinear systems replaced with linear systems, then robust controller is designed for this linearzed system to control real nonlinear system. Weather, after feedback linearization, robust controller easily can be designed for this system to cope with uncertainties on practical nonlinear system. Finally this new technique is compared with Linear Quadratic Regulator (LQR). Key-Words: Quantitative feedback theoryNonlinear control-Feedback linearization-Robust control-Linear Quadratic Regulator

متن کاملRobust Feedback Linearization Control for Reference Tracking and Disturbance Rejection in Nonlinear Systems
Most industrial processes are nonlinear systems, the control method applied consisting of a linear controller designed for the linear approximation of the nonlinear system around an operating point. However, even though the design of a linear controller is rather straightforward, the result may prove to be unsatisfactorily when applied to the nonlinear system. The natural consequence is to use ...
