Research on Backstepping Model Free Control Method Based on Command Filter

Abstract

Dynamic models of course channels of small unmanned helicopters with different types and different parameters are different, and the establishment of course channel model is complex. It is necessary to research free model control methods without relying on the mathematical models. As one of the most important methods in model free control fields, intelligent control method has drawn extensive attention of scholars. But it is in the stage of theory research, and the actual application is not much. This paper tries a design of course channel controller of helicopters with the intelligent control method. Depending on the observer performance, the paper puts forward the model free self-adaptive control-filtration backstepping control method for the marine power system. The two developing model free self-adaptive backstepping control command filters mainly solve three problems. The simulation results show that this method not only ensures the stability of the closed-loop control system of the control marine electric power system, but also can determine the speed state and the unknown dynamic model.
