Structure of a Viscoplastic Flow During the Mold-Filling Process

The flow of a viscoplastic fluid during the filling of a flat vertical channel was studied. The mathematical problem was formulated based on the complete equations of motion and natural boundary conditions on a free surface; the problem was solved by the finite-difference method. For shock-capturing, the Schwedoff–Bingham rheological equation was regularized. A parametric study of the flow characteristics and behavior of the free boundary was performed depending on the main parameters of the problem. The characteristic flow structures were demonstrated depending on the ratio of viscous, gravitational, and plastic forces in the flow.

An iterative approach for the discrete‐time dynamic control of Markov jump linear systems with partial information

The , and mixed dynamic output feedback control of Markov jump linear systems in a partial observation context is studied through an iterative approach. By partial information, we mean that neither the state variable x(k) nor the Markov chain θ(k) are available to the controller. Instead, we assume that the controller relies only on an output y(k) and a measured variable coming from a detector that provides the only information of the Markov chain θ(k). To solve the problem, we resort to an iterative method that starts with a state‐feedback controller and solves at each iteration a linear matrix inequality optimization problem. It is shown that this iterative algorithm yields to a nonincreasing sequence of upper bound costs so that it converges to a minimum value. The effectiveness of the iterative procedure is illustrated by means of two examples in which the conservatism between the upper bounds and actual costs is significantly reduced.
