Formal specification languages are traditionally supported by theorem provers, but recently model checkers have proven to be useful tools. In this paper we present Eboc, an explicit state model checker for Event-B. Eboc is based on lazy techniques that allow it to fairly perform an exhaustive state space search without bounding the size of the sets used in the specification. We describe the imp...

A method for identification of a synchronous generator is suggested in this paper. The method uses the theoretical relations of machine parameters and the Prony method to find the state space model of the system. Such models are useful for controller design and stability tests. The proposed identification method is applied to a third order model of a synchronous generator. In this study, the fi...

We tackle the fault diagnosis problem using conditionally Gaussian state space models and an efficient Monte Carlo method known as Rao-Blackwellised particle filtering. In this setting, there is one different linearGaussian state space model for each possible discrete state of operation. The task of diagnosis is to identify the discrete state of operation using the continuous measurements corru...

power electronic converters are non-linear time-dependent systems whose exact analysis without the use of computers is very difficult, and even using computer softwares requires a long time. use of the state space averaging method, as will be mentioned, in addition to simplifying the analysis procedure which is a result of converting a time-dependent system to a time-independent one, reduces th...

This article presents an application of the first order sliding mode control in order to damp the mechanical vibrations of a flexible one-link manipulator using piezoceramic actuators. The flexible manipulator, seen as a multiple inputs multiple outputs system is decoupled using state feedback scheme. The model of the system is deduced using the finite element method, and its response to a cont...

This paper proposes a new method for computing stable rational doubly coprime factorizations from a given transfer matrix. In contrast to the well-known method which requires a state space representation, the proposed method makes full use of polynomial matrices, and the whole operation is carried out directly in the frequency domain. Furthermore, the paper clarifies the meaning of the obtained...

This paper presents a numerical method for the characterization of Markov-perfect equilibria of symmetric differential games exhibiting coexisting stable steady states. The method relying on the calculation of ’local value functions’ through collocation in overlapping parts of the state space, is applicable for games with multiple state variables. It is applied to analyze a piecewise determinis...

In this paper we study a number of problems in the context of rational representations of behaviors. In that context, a given proper real rational matrix can represent three behaviors. In the first place it can represent an input-output behavior. Secondly it can represent the kernel behavior of the rational ’differential operator’ associated with the rational matrix. Thirdly, it can represent t...
