8th International IFAC Symposium on Dynamics and Control of Process Systems INVENTORY REGULATION AND SYNCHRONIZATION OF DYNAMIC SUPPLY CHAINS BY NONLINEAR BOUNDED PI CONTROL
نویسندگان
چکیده
A nonlinear bounded PI control for inventory level regulation, and for production and incoming rate synchronization in linear dynamic supply chains is proposed. Control boundedness is required to satisfy physical and operational limitations. The control varies and synchronizes the production and incoming rates while regulating the inventory levels. The dynamic models allow reckoning multi-product and multi-purpose systems by considering production ratios. For regulation purposes, PI techniques are introduced via nominal references. A stability analysis based on linearization is performed. Simulations of a multi-product petrochemical company show the controller performance. Copyright c © 2007 IFAC

Hybrid Control to Approach Chaos Synchronization of Uncertain DUFFING Oscillator Systems with External Disturbance
This paper proposes a hybrid control scheme for the synchronization of two chaotic Duffing oscillator system, subject to uncertainties and external disturbances. The novelty of this scheme is that the Linear Quadratic Regulation (LQR) control, Sliding Mode (SM) control and Gaussian Radial basis Function Neural Network (GRBFNN) control are combined to chaos synchronization with respect to extern...
متن کاملP-64: Strategies to Optimize Reproductive Efficiencyby Regulation of Ovarian Function inyak (Poephagus Grunniens L.)
Background: To design a pre-Ovsynch hormonal strategy in yaks in order to increase the ovulatory response to the first GnRH injection of Ovsynch so that overall synchronization rate to Ovsynch could be improved. Materials and Methods: Non-lactating cyclic yak cows (n=33) were assigned to receive either no treatment before Ovsynch (control) or 0.375mg of PGF2(PreP) followed 2 d later by 10 g of ...
متن کاملThe Attributed Pi Calculus
The attributed pi calculus (π(L)) forms an extension of the pi calculus with attributed processes and attribute dependent synchronization. To ensure flexibility, the calculus is parametrized with the language L which defines possible values of attributes. π(L) can express polyadic synchronization as in pi@ and thus diverse compartment organizations. A non-deterministic and a stochastic semantic...
متن کاملComputational Intelligence Applied to Nonlinear Dynamics and Synchronization
In general, to efficiently deal with modeling of complex nonlinear dynamical systems three essential tasks amongst others are involved, namely understanding, predicting, and explaining. The understanding task aims at developing mathematical models of systems relying on available data, measurements and observations in a bottom-up fashion. This allows identifying the system’s dynamics including t...
