Inferential control with the aid of modified QPLS-based soft sensor for an industrial FCCU fractionator
A modified quadratic partial least squares (MQPLS) algorithm based on non-linear constrained programming is proposed, in which a sequential unconstrained minimisation technique is employed to calculate the outer input weights and the parameters of inner relationship. Other existing quadratic partial least squares (QPLS) algorithms are also reviewed and compared with the proposed MQPLS in the ap...
متن کاملInferential Control Based on a Modified Qpls for an Industrial Fccu Fractionator
A modified Quadratic Partial Least Squares (MQPLS) algorithm based on nonlinear constrained programming is proposed. Sequential Unconstrained Minimization Technique (SUMT) is employed to calculate the outer input weights and the parameters of inner relationship. It was found that MQPLS can not only explain more of the underlying variability of the data, but also has improved modelling and predi...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

15 صفحه اولArtificial Intelligence for Inferential Control of Crude Oil Stripping Process
Stripper columns are used for sweetening crude oil, and they must hold product hydrogen sulfide content as near the set points as possible in the faces of upsets. Since product quality cannot be measured easily and economically online, the control of product quality is often achieved by maintaining a suitable tray temperature near its set point. Tray temperature control method, however, is n...
