This paper extends to non-controllable linear systems over rings the property FCs (s > 0), which means “feedback cyclization with s inputs”: given a controllable system (A, B), there exist a matrix K and a matrix U with s columns such that (A + BK, BU) is controllable. Clearly, FC1 is the usual FC property. The main technique used in this work is the obtention of block decompositions for system...

This paper studies near-controllability of a class of discrete-time bilinear systems via a root locus approach. A necessary and sufficient criterion for the systems to be nearly controllable is given. In particular, by using the root locus approach, the control inputs which achieve the state transition for the nearly controllable systems can be computed. Furthermore, for the non-nearly controll...

In this paper, we study the control system associated with the incompressible 3D Euler system. We show that the velocity field and pressure of the fluid are exactly controllable in projections by the same finite-dimensional control. Moreover, the velocity is approximately controllable. We also prove that 3D Euler system is not exactly controllable by a finite-dimensional external force.

an optimal desirability function method is proposed to optimize multiple responses in multiple production scenarios, simultaneously. in dynamic environments, changes in production requirements in each condition create different production scenarios. therefore, in multiple production scenarios like producing in several production lines with different technologies in a factory, various fitted res...

in many real systems in which a state variable should be controlled for being in appropriate range, the length of control (review) intervals is taken to be constant. in such systems, when the cost of reviews and out-of-range values of the state variable are considerable, this method may not be optimal. in this paper we let the length of review intervals to be variable during each operating cycl...

Assuming a general linear model with unknown and possibly unequal normal error variances, the interest is to develop a one-sample procedure to handle the statistical problems involving point estimation, confidence region, and general linear hypotheses on regression parameters. The sampling procedure is to split up each single sample of size ni at a controllable regressor’s data point into two p...

A vortex-bright soliton can precess around a fix point. Here, we find numerically that the fixed point and associated precessional orbits be shifted by applying constant driving force on bright component, displacement is proportional to with minus sign. This robust dynamics then discussed theoretically treating as an effective particle, explaining observed predicting new ones are subsequently c...

This paper concerns the problem of testing from a finite state machine (FSM) M modelling a system that interacts with its environment at multiple physically distributed interfaces, called ports. We assume that the distributed test architecture is used: there is a local tester at each port, the tester at port p only observes events at p, and the testers do not interact during testing. This paper...

With rapid smart grid technology development, the customer can actively participate in demand-side management (DSM) with the mutual information communication between the distributor operation company and the smart devices in real-time. Controllable load management not only has the advantage of peak shaving, load balance, frequency regulation, and voltage stability, but is also effective at prov...
