摘要：
This paper presents an l(1)-norm optimal state feedback controller for two-dimensional linear time invariant (LTI) systems with decoupled dynamics and a single control input. The controller is successfully applied to the problem of N-removal in activated sludge processes, both in simulation and on a pilot plant fed with real municipal wastewater. It optimises the moments at which the plant's aerators are switched on/off. Improvement of operation strategies for the process of N-removal from wastewater is an important topic due to tightening government legislations with the objective to protect the aquatic environment.
