Special Issue Information

Dear Colleagues,

Although research in the field of dynamics and oscillations dates back to ancient times, some problems still remain unsolved;  these issues primarily concern non-linearities in systems or processes. The aim of this Special Issue is to publish the results of research on the influence of both physical and geometric nonlinearities on system dynamics. Hence, this issue focuses on research in the dynamics and vibrations of nonlinear mechanical systems and processes. The following topics are of interest:

  • Mathematical modelling of nonlinear dynamical and vibration systems and processes;
  • New analytical and numerical solving procedures for strong nonlinear oscillators;
  • Nonlinear phenomena in dynamic systems;
  • Bifurcation and deterministic chaos;
  • Control in nonlinear oscillators;
  • Analogies between nonlinear mechanical and other systems;
  • Application of nonlinear oscillators in applied sciences and engineering.

The Special Issue on “Phenomena in Nonlinear Dynamical Systems: Theory and Application” welcomes not only submissions on the aforementioned topics but also on all recent research covered by the topic in the title. The call is open to a broad thematic range of papers covering recent applications of dynamics, vibration and control theory.

This paper presents a new approach to the nonlinear model predictive control (NMPC) of an underactuated overhead crane system developed using a data-driven prediction model obtained utilizing the regularized genetic programming-based symbolic regression method. Grammar-guided genetic programming combined with regularized least squares was applied to identify a nonlinear autoregressive model with an exogenous input (NARX) prediction model of the crane dynamics from input–output data. The resulting prediction model was implemented in the NMPC scheme, using a particle swarm optimization (PSO) algorithm as a solver to find an optimal sequence of the control actions satisfying multi-objective performance requirements and input constraints. The feasibility and performance of the controller were experimentally verified using a laboratory crane actuated by AC motors and compared with a discrete-time feedback controller developed using the pole placement technique. A series of experiments proved the effectiveness of the controller in terms of robustness against operating condition variation and external disturbances. Full article
