Toward an implementation of hierarchical hybrid control systems for the integrated operation of industrial complexes

摘要

This paper proposes a software/hardware architecture to achieve the implementation of a global control strategy for continuous production industrial complexes. The industrial complex is described by a set of continuous process units, coordinated hierarchically by Discrete Event Dynamic Systems (DEDS) parametrized by human decisions. The concept presented in this paper uses a hierarchical structure in three levels. The first level, the Direct Control Level (DCL), is implemented as a Hybrid System. The second level, the Decision Level (DL), performs the coordination and optimization tasks to define the set of operating points to control the Continuous Process Units under a defined control strategy. The third level, the Planning Level (PL), is the uppermost level where the overall control strategy is defined taking into account internal and external factors. In addition, this paper shows the computational support (hardware, software, and networking) which is necessary to implement the proposed integrated scheme. (authors). 14 refs., 6 figs.
