Synchronization and Control of Attitude for Spacecrafts:
The topic of this paper is to control and synchronize sphere-shaped spacecrafts in a leader-follower synchronization scheme. In order to achieve this objective, a nonlinear mathematical model of the vehicles has been developed. The design is based on rigid body dynamics where the vessel is actuated by means of three orthogonally mounted reaction wheels. The attitude dynamics is derived using Eu...
متن کاملObservability and measurement allocation analysis for networked systems
This paper deals with the strong state observability analysis for Networked Systems which are composed of interconnected subsystems that exchange data over communication networks. More precisely, we interest to determine which data or measurements must arrive via the network to a subsystem in order to ensure that a local observer can estimate its state vector. The proposed approach is based on ...
متن کاملRcd Rules and Power Systems Observability
Power system state estimation is a process to find the bus voltage magnitudes and phase angles at every bus based on a given measurement set. The state estimation convergency is related to the sufficiency of the measurement set. Observability analysis actually tests this kind of problem and guarantees the state estimation accuracy. A new and useful algorithm is proposed and applied in this pape...
متن کاملObservability, Redundancy, Reliability and Integrated Design of Measurement Systems
The problem of sensor placement is considered. The quality of diagnosis depends on the number and location of measurements. We first deal with this dependence by analysing the observability. The concepts of degree of redundancy is introduced. The criterion of reliability is useful for designer to enhance the reliability of the measurement system. When some variables are required for the control...
متن کاملON CONTROLLABILITY AND OBSERVABILITY OF FUZZY CONTROL SYSTEMS
In order to more effectively cope with the real world problems of vagueness, imprecise and subjectivity, fuzzy event systems were proposed recently. In this paper, we investigate the controllability and the observability property of two systems that one of them has fuzzy variables and the other one has fuzzy coefficients and fuzzy variables (fully fuzzy system). Also, sufficient conditions for ...
