Discrete-Time Model of a Two-Speed PowerShift suitable for Real-Time Control and Simulation
Riccardo Morselli, Davide Tebaldi, Roberto Zanasi
In this paper, a new discrete-time approach to model the clutches engagement/disengagement in a two-speed powershift is proposed. The core idea is the development of a model for th…
An Approach for the Qualitative Graphical Representation of the Describing Function in Nonlinear Systems Stability Analysis
Davide Tebaldi, Roberto Zanasi
The describing function method is a useful tool for the qualitative analysis of limit cycles in the stability analysis of nonlinear systems. This method is inherently approximate;…
Efficient and Robust Modeling of Nonlinear Mechanical Systems
Davide Tebaldi, Roberto Zanasi
The development of efficient and robust dynamic models is fundamental in the field of systems and control engineering. In this paper, a new formulation for the dynamic model of non…
On the Analysis of Qualitative Nyquist Plots
Davide Tebaldi, Roberto Zanasi
A powerful tool in control and systems engineering is represented by Nyquist plots, for which a qualitative representation often gives a clearer visualization of the frequency resp…
The Construction of Asymptotic Bode Plots: A New Direct Method
Davide Tebaldi, Roberto Zanasi
Bode plots represent an essential tool in control and systems engineering. In order to perform an initial qualitative analysis of the considered systems, the construction of asympt…
