Title: Practical tracking by output feedback for a class of nonlinearly parameterized systems with unknown control coefficients
Abstract: The practical tracking control by output feedback was considered for a class of nonlinearly parameterized systems with unknown control coefficients.By introducing the appropriate coordinate transformation,the original system was transformed into a new system without uncertain control coefficients.Then,a suitable high-gain observer was constructed and the tracking controller by output feedback was successfully designed using the backstepping technique.The simulation result showed that if the design parameters were chosen suitably,the designed controller guaranteed the closed-loop system states to be globally bounded,and the tracking error to converge to the prescribed small neighborhood of the origin after enough long time.
