In the later stage of the production and development of HB Oilfield, the oil reservoir fluid type is complex.With the development of multi-layer system.The reservoir variables between different types of oil and gas reservoirs are large, and the relationship between oil and water is complex.Most main oil layers have high water drives, and the actual
This study addresses an adaptive neural funnel fault-tolerant control problem for a class of strict-feedback nonlinear systems with actuator faults and input dead zone.To guarantee the boundedness of the tracking error, a modified transformation for funnel Consumables error is devised and incorporated into the control design process.To manage unkno
