The paper presents common cascade control architecture where specific kind of redundancy could be considered. There are different approaches how to increase the reliability of networked control systems. Common approach uses redundant components in control system i.e. passive or active redundancy. We deal with quasi-redundant subsystems (shared redundancy)(More)
This paper presents results of modelling and analysis of Network Control Systems (NCS) using the reconfiguration strategies in case of individual networks faults. In general the NCS as all systems follows its mission which should be accomplished with guarantee. The system mission can be disturbed or interrupted by failures which occur with some probability.(More)
Analysis of adaptive control and model design in adaptive control is discussed in this paper. In the first and second part of the paper, basic tendency in adaptive control is analysed. The main aim of the paper is to design the controlled system model or reference model of the controlled system behaviour. With regards to knowledge in adaptive control fuzzy(More)
The paper presents features and implementation of a shared redundant approach to increase the reliability of networked control systems. Common approaches based on redundant components in control system use passive or active redundancy. We deal with quasi-redundant subsystems (shared redundancy) whereas basic features are introduced in the paper. This type(More)
In the area of sequential computing the RAM (Random Access Machine) has successfully provided model of computation, in the realm of parallel computing there has been no similar success. The need for such unifying parallel model is growing by the demand for performance and the diversity among machines. This survey is trying briefly to describe models of(More)
