Adaptive control of two-cell selective catalytic reduction systems

In this work, we investigate the integrated study of closed-loop control for Diesel engine two-cell selective catalytic reduction (SCR) systems. With the generated references, an adaptive backstepping controller is adopted to control the two-cell SCR system. Experimental tests are carried out for the US06 test cycle. It infers from the test results that the control performance with the designed dynamic generators has some advantages over the performance with constant references and the lumped case.
