Abstract
In the dynamically substructured system (DSS) testing technique, a controller that synchronises the responses of physical and numerical substructures is an essential part of the testing scheme to ensure synchronisation fidelity. This paper discusses a novel approach that generates a two-degree-of-freedom (2-DOF) output feedback controller for multi-input, multioutput (MIMO) DSS via control synthesis. This 2-DOF output feedback controller yields robust stability and robust performance of the physical/numerical substructure synchronisation and enables controller tuning in the frequency domain. Simulation and experimental results have been shown to validate the efficacy of the method.
Highlights
The dynamically substructured system (DSS) approach [1] is a testing technique that combines fullsize physical components with a real-time numerical simulation of the remaining components in order to replicate the dynamical behaviour of a complete system
The concept of this type of testing was first proposed as hardware-in-the-loop simulation (HiLS) and hybrid simulation (HS), which have been implemented in various fields including the railway industry [2, 3, 4]
Conclusions and further work In this paper, a systematic state-space approach was provided for the design of a 2-DOF outputfeedback controller for DSS
