    We present a hybrid representation for modeling of mechatronic systems. This representation consists of a linear graph and block diagrams and supports our concept of composable simulation. By composable simulation we mean the ability to automatically generate simulations from individual component models through manipulation of the corresponding physical components in a CAD system. The approach is ... View full abstract»

    Time optimal control of nonlinear systems is considered. To find the optimal horizon, a sequence of fixed-horizon problems of minimizing an auxiliary cost functional is solved by gradient methods, with the use of adjoint trajectories. Basically, the control switching times are decision variables. The proposed computational methods of search for optimal horizon are based on an estimation-continuati... View full abstract»

    A formal framework based on the object-oriented paradigm for hybrid control systems modelling is illustrated. One of the peculiar elements of the proposed approach is modularity, which is realised through the definition of a basic hybrid module, that can be recursively aggregated. Particular attention has been paid in the formal definition of the basic module, classifying its discrete state transi... View full abstract»

    It has been proven that the generalized Lotka-Volterra equations can express arbitrary continuous functions if there are sufficient hidden nodes that are not assigned by observational data. We show that the generalized Lotka-Volterra equations encompass a description of the same structure as do artificial neural networks. Since the equations can be used as a universal modeling framework, we refer ... View full abstract»
