Propuesta De Un Control Supervisor Para Regular La Tensión De Salida De Un Convertidor Boost Utilizando La Entropía Aproximada Como Detector De Eventos

The theory of sliding mode control is used to synthesize a controller for the continuous dynamics. Now, to solve both the problem of discontinuity as the problem of insensitivity to uncertainty in the load resistance of such converter had to design a hybrid output feedback controller to guarantee the output voltage to a desired value. Particularly an approximate entropy (ApEn) concept is used as an innovative method that could detect any event generated on the continuous time dynamics in the hybrid system. It was found that the hybrid plant supervisor provides good results in terms of robustness to disturbances, maintaining a good dynamic response.

In this article we propose to extend the idea of using of multiresolutional models [1] to construct a framework for supervisory control based upon a fuzzy and agent event detection approach. The suggested approach is validated using discrete-event simulation techniques applied to a hydro-pneumatic system.

An integration architecture for the automation of a continuous production complex

A variety of factors must be taken into account, such as their different components ͑e.g., production units control systems, planning systems, financial systems, etc.͒, the interaction among them, and their different behavior ͑continuous or discrete͒. Moreover, the difficulty of this process is increased by the fact that each component can be viewed in a different way depending on the kind of decisions to be made, and its specific behavior. Modeling continuous production complexes as a composition of components, where, in turn, each component may also be a composite, appears to be the simplest and safest way to develop integrated automation systems. In order to provide the most versatile way to develop this kind of system, this work proposes a new approach for designing and building them, where process behavior, operation conditions and equipment conditions are integrated into a hierarchical automation architecture.

Supervisory control design based on hybrid systems and fuzzy events detection. Application to an oxichlorination reactor

The fuzzy event detector is a linguistic model, which synthesizes complex relations between process variables and process events incorporating experts' knowledge about the process operation. This kind of detection allows the anticipation of appropriate control actions, which depend upon the selected membership functions used to characterize the process under scrutiny. The proposed supervisory control scheme was successfully implemented for an oxichlorination reactor in a vinyl monomer plant. This implementation has allowed improvement of reactor stability and reduction of raw material consumption.
