The object model for cyber-physical system's in state space (on the example of the pavement compaction process)

Abstract

We has considered results of object model theoretical description of the cyber-physical system – the compaction process of the road surface with a vibration roller, based on the method of the state space. The working body of the roller includes a vibration drum with a built-in unbalance shaft. The mathematical model of the process of interaction of the object with the compacted road-building material takes into account the mass of the main structural elements of the vibration roller and the mass of the compacted road material. To describe the characteristics of the compacted material, a rheological model of the viscoelastic Kelvin-Voight body is used. The suitability of the obtained mathematical model based on the results of simulation of the system in the Matlab/Simulink program is experimentally confirmed.
