nonlinear lumped-parameter model of a piezoelectric stack A, ctuator has been developed to describe actuator behavior for purposes of control system analysis and design, and, in particular, for microrobotic applications requiring accurate position andor force control. In formulating this model, the authors propose a generalized Maxwell resistive capacitor as a lumped-parameter causal representa...

In this paper, the authors present a 0D fluid dynamic model of vane pump used to refill tanks with fuel. The is entirely developed in OpenModelica environment, where have created specific libraries elements suitable for physical modelling power components and systems. Among different approaches, zero-dimension (0D) fluid-dynamic positive displacement machines study many aspects as: instantaneou...

Modelling of heterogeneous systems is always a trade-off between model complexity and accuracy. Most libraries of object-oriented, equation-based, multi-physical simulation tools are based on lumped parameter description models. However, there are different ways of including spatial dependency of certain variables in the model. One way that might be quite difficult is to manually discretize the...
