Abstract

This paper is focused on modeling, simulation and validation of the mathematical model of a loading bridge by comparison to the real system. A Lagrangian modeling method is presented to define a mathematical model of the loading-bridge dynamical system. Using the Matlab–Simulink simulation environment we have estimated the parameters and validated the model with regard to the experiments on the real device.  The discrepancy between the simulated and the measured responses was adequate. Hence, we can conclude that the developed nonlinear model provides a satisfactory description of real system behaviour. Using the model, we designed a fuzzy controller for controlling load position and load height. The obtained controller has also been tuned and tested on the real device.
