Abstract:This paper proposes a position controller to handle three problems in the control of an electro-hydraulic servo system. The first two problems are about the nonlinearities and the uncertainties of the electro-hydraulic servo system, and the third one is the chattering problem caused by adopting sliding mode control. The proposed controller is called a Switch Controller, for its control output switches between the outputs of two controllers, a Nonlinear Controller and a conventional Linear Controller. The Nonli… Show more
