摘要
Dissolved oxygen (DO) concentration is a key parameter in wastewater treatments. It directly determines the effluent quality. For the uncertainties and external disturbances, a finite time extended state observer (FTESO) is designed to estimate the uncertainties and disturbances in a finite time. Controller is designed to keep the DO concentration in a desired level. Benchmark simulation model No.1 (BSM1) is used to simulate a wastewater treatment process. Numerical results are presented to verify the method.
