A new approach to model multi-agent systems with hierarchical colored Petri nets is introduced. Every agent has its colored Petri net system, when agents are composed into a MAS, we get hierarchical colored Petri net system of the multi-agent system, properties of the hierarchical colored Petri net system, such as reachability, deadlock detection and avoidance, fairness can be used to analyze d...

The analysis of changes in water quality in a monitoring network system is important because the sources of pollution vary in time and space. This study utilized analysis of the water quality index calculation, hierarchical cluster analysis, and mapping. This was achieved by assessing the water quality parameters of the samples collected from Galma River in Zaria, Northwestern Nigeria in wet an...

[Abstract] Quantization problem in digital control system have attracted more and more attention in these years. Normally, a quantized variable is regarded as a perturbed copy of the unquantized variable in the research of quantization effect, but this model has shown many obvious disadvantages in control system analysis and design process. In this paper, we give a new model for quantization ba...

The scope of the CKBE application can include Fuzzy control systems and learning Fuzzy – genetic systems [4] based on the Pittsburgh approach. In the very first ones, they can check the correct working of the control system and can detect any changes in the system to be controlled. In the case of the learning systems, CKBE allows to evaluate the behaviour of the generate individuals, in a previ...

In the discrete modeling approach for hybrid control systems, the continuous plant is reduced to a discrete event approximation, called the DES-plant, that is governed by a discrete event system, representing the controller. The observability of the DES-plant model is crucial for the synthesis of the controller and for the proper closed loop evolution of the hybrid control system. Based on a ve...

A representation of the limit occupational measures set of a control system in terms of the vector function defining the system’s dynamics is established. Applications in averaging of singularly perturbed control systems are demonstrated.

In this paper we address the problem of closed loop stabilization of switched control systems. First we propose a general definition of closed loop switched solution of a control system. Then we use it in order to get a stabilizability result for planar bilinear systems. This result is finally compared with existing literature.

The center manifold theorem is a model reduction technique for determining the local asymptotic stability of an equilibrium of a dynamical system when its linear part is not hyperbolic. The overall system is asymptotically stable if and only if the center manifold dynamics is asymptotically stable. This allows for a substantial reduction in the dimension of the system whose asymptotic stability...

This paper presents a general approach to design a partially stabilizing controller for nonlinear systems. In this approach, the nonlinear control system is divided into two subsystems, which are called the first and the second subsystems. This division is done based on the required stability properties of system’s states. Furthermore, it is shown that partial control makes the possibility of c...
