LMI-based invariant like nonlinear state observer for anaerobic digestion model
2017 25th Mediterranean Conference on Control and Automation (MED)
Darouach. LMI-Based invariant like nonlinear state observer for anaerobic digestion model. Abstract-This note deals with the design of an invariant like nonlinear state observer for a two step (acidogenesismethanogenesis) mass balance nonlinear model. In order to ensure the stability of the estimation error, a new LMI condition is proposed. The feasibility of this LMI is enhanced due to the use of a suitable reformulation of the Youngs inequality. Actually, additional decision variables aredoi:10.1109/med.2017.7984197 dblp:conf/med/DraaAVZD17 fatcat:gos4yzw4aza2rox6qpuypjuoei
