Decentralized supervisory control is investigated by considering problem formulations that model systems whose specifications are given as global constraints but whose solution is described by local controllers. A necessary and sufficient condition is given for the existence of a solution to the problem of finding decentralized supervisors that ensure that the behavior of the closed-loop system lies in a given range. Where the range of behavior can be described by regular languages, it can be effectively tested whether the decentralized control problem is solvable;in this case, a procedure is given to compute the associated supervisors.
An improved global convergent computed torque algorithm is presented for adaptive control of rigid robots. The algorithm eliminates the restrictive assumption on the boundedness of the inverse of the estimated inertia...

Robustness properties of non-companion representation of linear systems, studied using a criterion due to contribution of Drcuzenouic 1969, are retained to a limited extent only. Hajor drawback of this approach, utilizing the facilitating fact of B(CB)^C being a projector such that disturbances or parameter variations belong to the range space of input matrix B, is that the extent of the robustness is not determined. In this paper, quantitative measures are introduced for assessing the extent of lack of robustness. Method is based on singular value analysis of closed-loop state matrix F in sliding mode introducing the simple stability criteria.

The innovating impact of modern information technologies in computer based systemscontrol is causing conceptual changes in energy control and management systems. Variable-structure control strategies can be introduced into such systems in several ways. The use of symmetric VS controls enables handling the uncertainty in systems models. The superiority of VS control over continuous control is demonstrated using a representative case study

The company under investigation is divided into three strategical units (profit center’s): “bank-, sawmill- and industry automation”. On the other hand of the matrix- organisation of this company there exist the sections marketing, finance and system- technology. It is intended to find an operating characteristics acquisation system (OCA) which is embedded in a computer integrated manufacturing (CIM) solution. To reach this goal the project will be realised in two steps, first of all to introduce the personnel time acquisition and afterwards to develop the order related data acquisition system. The concept of this OCA solution has to take into account several frame conditions. On the one hand an existing LAN has to be used to transport the OCA data. On the other hand the data management will be realised by means of a relational database management system under SQL, in order to obtain an open interface to ensure an expandability of the data base for the second level and the integration of the order related data acquisition in the non production areas. The complexity of the project should be reduced by using standard software packages in separated modules.

Quality demands under the pressure of international competition can be satisfied only specific for small and medium sized enterprizes with respect to the standards ISO 9000 to ISO 9004. The descriped and self developed CAQ system consists of 20 modules. All of them are integrated in an existing CIM concept. The CAQ system has been considered at creation time of the existing CIM system. Therefore a relational CIM data base in addition to the PPS database are connected to the CAQ data base. The modular software is arranged in layers and supports the client/server principle. A network (ethernet) with MS-DOS PC’s and Unix- Workstations are the main hardware components.
