the problem of robust fault detection and isolation in robotic and mechatronic systems described by nonlinear models with non-smooth nonlinearities is considered. So-called logic-dynamic approach to construct the diagnostic observer with non-smooth nonlinearities by linear methods is considered. the method which allows obtaining full set of solutions with minimal sensitivity to the disturbance is suggested. this set of solutions can be used to choose the optimal solution with maximal sensitivity to the faults.

Statistical analysis and modelling of various phenomena are well established in nowadays industrial practice. However, the traditional approaches neglecting the true properties of the phenomena still dominate. Among others, this includes also the cases when a variable with bounded range is analyzed using probabilistic distributions with unbounded domain. Since many of those variables nearly fulfill the basic conditions imposed by the chosen distribution, the properties of used statistical models are violated rather rarely. Still, there are numerous cases, when inference with distributions with unbounded domain may lead to absurd conclusions. this paper addresses this issue from the Bayesian viewpoint. It briefly discusses suitable distributions and inferential methods overcoming the emerging computational issues.

the improvement of energy efficiency in automation and robotic systems still has high significance in engineering research. this paper presents experimental results of minimum energy trajectory optimization for multi-axis manipulators using electrical energy exchange via the shared inverter DC link. thus, existing simulation findings demonstrating the potential of the proposed minimum energy optimization approach are validated. In this context, a global optimization method is applied utilizing an advanced cost function formulation that is based on an energy flow model including all servo drive components. After the validation of the utilized system model, increased efficiency improvements are proven and compared to established methods. the presented approach as well as the experimental results are fully transferable to any kind of multi-axis system comprising DC link energy supply.

the study of properties of switched and hybrid systems gives rise to a number of interesting and challenging mathematical problems. this paper aim to briefly survey recent results on stability and controllability of switched linear systems. First, the stability analysis for switched systems is reviewed. We focus on the stability analysis for switched linear systems under arbitrary switching, and we highlight necessary and sufficient conditions for asymptotic stability.

A new variant of the genetic algorithm for finding the location and size of small holes in the domain described by the non-linear boundary value problem is considered. the expansion of the shape functional defined in non-linear domain is provided in order to determine the form of topological derivative. the value of topological derivative is used for computing the probability density applied later to generate location and size of holes by the genetic algorithm.

the paper presents connections between criteria which make three types of objects possible to recognize, namely: edges, planes and corners. these criteria can be applied while a binaural sonar system is used. It is shown that the criteria are specific forms of a general equation. the form of the equation depends on a single coefficient. In the paper the meaning of this coefficient is discussed. the constructions of the objects arrangements are presented which are bound with other values of the coefficient.
