A Systems Approach for Modelling Mechatronics Systems Bassam A. Hussein Production and Quality Engineering Department, The Norwegian University of Science and Technology, NTNU, Trondheim, Norway Received on December 3,1997 ABSTRACT This paper presents a unified approach based on utilizing multidimensional arrays in order to model the physical and logical properties of mechatronics systems. A mechatronics system model consists of two interacting submodels.A submodel that describes aspects related to energy flow in the physical system, and another submodel that describes aspects related to information flow in the control system. The multidimensional array based approach of modelling provides us with the possibility to use one terminology and the same formalism for modelling both subsystems. The consequence of using the same formalism is that simulation of the mechatronics system can be performed using only one simulation environment Keywords: Mechatronics, System, Modelling 1. INTRODUCTION Mechatronics system is defined as the synergetic integration of mechanical engineering with electronics, and intelligent computer control in the design and manufacturing of industrial products and processes [5]. The components of mechatronics systems must be designed concurrently, that is, the constraints imposed on the system by each discipline must be considered at the very early stages. Therefore, proper system design will depend heavily on the use of modelling and simulation throughout the design and prototyping stages. The integration within a mechatronics system is performed through the combination of the hardware components resulting in a physical system and through the integration of the information processing system resulting in an intelligent control system [7]. The mechatronics system then, is the result of applying computer based control systems to physical systems. The control system is designed to execute
