Abstract Enabling transmission of state variables and controller command signals between physics-based model and physical or emulated PLC requires developing fast and synchronous communication interface. This research investigates four methods of interface communication: (a) reading/writing to text files, (b) serial communication, (c) TCP communication, and (d) shared memory. The shared memory interfacing method provides the best performance, reliability, and fidelity. It is validated by linking a representative PLC controller to a Simulink dynamic simulation model of a fully integrated space reactor power system with multiple closed Brayton cycle loops for energy conversion (DynMo-CBC). Transient performance results of the PLC controlled dynamic simulation model are identical to those obtained using the Simulink model with internal control.

Simulation Equation

The use of the traditional fabric simulation model evidently shows that it cannot accurately reflect the material properties of the real fabric. This is against the background that the simulation result is artificial or an imitation, which leads to a low simulation equation. In order to solve such problems from occurring, there is need for a novel model that is designed to enhance the essential properties required for a flexible fabric, the simulation effect of the fabric, and the efficiency of simulation equation solving. Therefore, the improvement study results will offer a meaningful and practical understanding within the field of garment automation design, three-dimensional animation, virtual fitting to mention but a few.
