Process Control Strategy for Oilfield Piezoelectric Control Layered Production Allocation

Focusing on the fluid flow control in oilfield piezoelectric control layered production allocation, an identification-free adaptive control strategy with expert amendment is proposed to solve the problem that it is hard to be controlled due to large time delay, nonlinearity, time variation and difficulty in establishing mathematical model of regulation process. In this control strategy, according to the past and current process information, the process output and trend can be estimated based on expert rules to amend the output of the identification-free adaptive control. The simulation result shows that this control strategy has good robustness and perfect fluid flow control for piezoelectric control layered production allocation process.
