Tracking Control Solution for Road Simulators: Model-based Iterative Learning Control Approach Improved by Time-domain Modelling

Abstract

 Fatigue and durability tests are very important to develop and to optimize mechanical structure used in automotive, defence technology.  Forces in application of a product developed or being developed are named as road data. After position, force and acceleration are collected during real world application, reproducing this data of measurements in laboratory brings with a complicated control problem, as another word, it is control research area. Nonlinear structure of hydraulic actuators and test specimen with changing model parameters and noises restricts tracking performance of standard control approaches. In this paper, to reproduce the road data, “Time domain Modal-based Iterative Learning Control “procedure is recommended. The control algorithm is applied on 2-poster test rig.
