In this article the disturbance attenuation problem arising in Failure Detection and Identification (FDI) using detection filters is discussed. The filter is designed using the general Fundamental Problem of Residual Generator(FPRG) algorithm and it is assumed that decoupling the failure modes from the deterministic disturbance is not possible. The disturbance attenuation is achieved by applying H ∞ filtering concepts. Numerical example is shown to demonstrate the effect, of the worst case disturbance rejection on residuals that are sensitive to failure directions.

In this paper, the intelligent space (iSpace) concept is applied for helping disabled or blind persons in crowded environments such as train stations, or airports. The main contribution of this paper is a general mathematical (fuzzy-neuro) description of obstacles avoidance method (walking habit) of moving objects (human beings) in a limited area scanned by the intelligent space. A mobile robot with extended functions is introduced as a mobile assistant robot, which is assisted by the iSpace. The mobile assistant robot (MAR) can guide and protect a blind person in a crowded environment with the help of the iSpace. The iSpace learns the obstacle avoidance method (walking habit) of dynamic objects (human beings) by tracing their movements. The learned walking habit is encoded in a mathematical structure and is sent to the control of MAR. control of MAR estimates the path of dynamical obstacles and helps to the blind person to avoid the collision. The prototype of the mobile assistant robot and simulations of some basic types of obstacle avoidance method (walking habit) are presented.

In this paper, we propose two methods aiming at updating geographic information system (GIS) urban maps using satellite high-resolution remote sensed images. Both methods are based on the input of a priori knowledge provided by GIS data, and a digital surface model (DSM). This article introduces theoretical aspects of our methods.

A control systems engineering approach, employing a two-level overall system architecture and different but compatible formalisms for system representation on the upper and lower levels, has been investigated in detail. One design alternative is based on employing fuzzy-system approximators and solving for the adaptive tracking of the given, arbitrary, desired system outputs. The other alternative is based on state equations of composite systems and the use of neural-network approximators to deal with uncertainties and control adaptation. In both alternatives similarity property of subsystems has been exploited. Both designs can be implemented within the standard computer process control technology, and are therefore believed to be promising in applied systems engineering.
This paper presents the model-based diagnosis in the framework of discrete-event systems. Timed automata are used as a discrete-event representation which is suitable for consistency-based diagnosis. The diagnostic st...
