Robust, Nonlinear Feedback Control

Abstract

This project has encompassed research in four areas of control theory, namely robust, fixed structure control, identification, adaptive cancellation, and nonlinear control. The robust, fixed structure control techniques have been implemented in a mat lab tool box for control design. The identification techniques include recursive methods with guaranteed convergence for high order linear systems. The adaptive cancellation methods provide disturbance rejection for systems with uncertain or time varying disturbance spectra with minimal system modeling. Nonlinear techniques for stabilizing unbalanced rotors and for finite time stabilization have been developed. Experimental implementation and validation of the control methods developed under this project was performed on several laboratory scale testbeds, including an acoustic noise experiment and an unbalanced rotating shaft experiment.
