In this note we consider the cooperative linear quadratic control problem. That is, the problem where a number of players, all facing a (different) linear quadratic control problem, decide to cooperate in order to optimize their performance. It is well-known, in case the performance criteria are positive definite, how one can determine the set of Pareto efficient equilibria for these games. In ...

by afternoon having changed to another state. In many domains it is important to reason about processes that change over time. Unfortunately, in many situations relevant data may not be available when the reasoning is done; there may be corrections to the data; or the state of the process may be changing. These problems are particularly evident in the reasoning involved in patient management. P...

Abstrad-Screening tools for control structure selection in the presence of model/plant mismatch are developed in the context of the Structured Singular Value (p) Theory. The developed screening tools are designed to aid engineers in the elimination of undesirable control structure candidates for which a robustly performing controller does not exist. The screening tools are examined on a multi-c...

Decentralized robust controller design problem for large-scale interconnected systems which involve uncertainties in the system matrices and uncertain time-delays is considered. An error bound, which accounts for the neglected interactions between the subsystem models and uncertainties in the interactions, in the subsystem models, and in the time delays is first derived using overlapping decomp...

Fertilizer application control in reason is the key technology to improve operation quality, reduce fertilizer pollution, and cut down costs of production. A control system of variable rate fertilizer is developed based on microcontroller chip in the paper. The system can automatically control flow dosage by adjusting feed gate opening size and changing hydraulic motor speed of fertilizer conve...

The dominant model of organisation control was developed by Ouchi and his colleagues. It predicts the choice among control modes as a function of the task context. It has two limitations. One is that it predicts the choice of control modes but not the effect of those choices on performance. The other is that it restricts that choice to a single control mode for a specific context and does not c...

Software agents have shown considerable promise in many fields. Thus, control structures for such software agents raise important research issues. This thesis goals are (1) to design control structures for software agents, (2) to solve real world problems with these models, and by doing this, (3) to discover some principles of control mechanisms of software agents. Therefore, the major question...

Traditional statistical process control charts used to monitor key process variables are based on the assumption that measurements are independent and identically distributed about a target value. In practice they are not and often are actually correlated. Reliance on univariate charts can lead to misleading conclusions. This paper addresses the methods for improving the quality of industrial p...

We consider the problem of a packet multiplexor that receives packets from multiple input flows, then forwards them to a single output channel. The multiplexor ensures a predefined forwarding rate for each flow. This is achieved as follows. The multiplexor assigns a timestamp to each received packet. When the channel becomes idle, the multiplexor forwards the packet with the smallest timestamp....
