Design of selective catalytic reduction systems controller for diesel engine using triple-step nonlinear method

Abstract: Urea selective catalytic reduction (Urea-SCR) is well known for exhaust gas aftertreatment in diesel engines. In this paper, for simultaneously achieving high conversion efficiency and low ammonia slip, a ammonia storage controller is designed to track the desired coverage ratio along the axial direction of a SCR catalyst using the triple-step method. Different from the existing nonlinear controller design methods, the design procedure is formalized as a triple-step deduction, and the derived controller consis… Show more

“…THE NONLINEAR TRIPLE-STEP CONTROLLER 1) STEADY-STATE-LIKE CONTROLIn the field of automotive engineering, maps are often used to characterize input-output relationships at steady state. Accordingly, a control input is obtained by checking reversely a map[35]-[37].Denote u s = [u 1s u 2s ] T as the control input while sideslip angular velocity β = 0 and yaw acceleration γ = 0, then F yf (β, γ , u 1s ) + F yr (β, γ , u 2s ) = mvγ(10) aF yf (β, γ , u 1s ) = bF yr (β, γ , u 2s )(11)…”
