The paper describes importance of the reactive power control basing on the failures and control problems in the Polish transmission networks. A detailed description of the operational difficulties is provided. The paper also presents a highly automated method identifying voltage control areas (VCA), areas prone to voltage instability, and reactive power reserves requirement ensuring voltage sta...

This paper reports on the initial development of the Smart Workkow for ISR Management (swim) system which has been designed to enable complex systems, business and software, to be controlled within the workkow management paradigm. The system exploits recent advances within the AI community in reactive control, scheduling and continuous execution. swim extends the workkow paradigm to respond to ...

The electric arc furnaces are a very large power load, determining the negative effects on the power quality (harmonics currents, unbalanced load, and reactive power). For a maximum efficiency of the power consumption it is necessary to use an automat system for control the harmonics filters, the reactive power compensation installation and the electrodes position, in order to obtain a high val...

This paper describes a reactive architecture handling the hybrid temporality of guided human-computer music improvisation. It aims at combining reactivity and anticipation in the music generation processes steered by a “scenario”. The machine improvisation takes advantage of the temporal structure of this scenario to generate short-term anticipations ahead of the performance time, and reacts to...

Synchronous languages allow a high level, concurrent, and deterministic description the behavior of reactive systems. Thus, they can be used advantageously for the programming of embedded control systems. The runtime requirements of synchronous code are light, but several critical properties must be fulfilled. In this paper, we address the problem of the software implementation of synchronous p...

This paper describes the hardware and software architecture of the Attempto RoboCup-99 team. We first present the design of our heavily modified commercial robotic base, the robot sensors and onboard computer. Then the robot control architecture which realizes a hybrid control, consisting of a reactive behavior based component and a planner component for more complex tasks is introduced. Also t...

This paper presents an approach to accelerate reactive processing via an external logic block that handles complex signal expressions. A reactive program, programmed in the synchronous language Esterel, is synthesized into a software component, running on the Kiel Esterel Processor, and a hardware component, consisting of simple combinational logic. The transformation process involves a two-ste...

In this report, we describe an approach that integrates a mathematical speci cation language with more traditional software design techniques to yield a practicable methodology for the speci cation of safety-critical control systems. To manage complexity and to foster separation of concerns, the system design model is divided into three views: the architectural view, speci ed with object and cl...

This paper discusses dynamic reconfiguration of applications at the architectural level. Current work on dynamic aspects of software architectures has focused on planned reconfigurations controlled from the outside. In this paper we present a different approach, using architectural agents. The agent-enabled architecture descriptions will be executable and have a mechanism to describe reconfigur...
