Process models using hardware in simulation loop

摘要

This paper describes two methods for realization of configurable time continuous linear and non-linear dynamical models. The first method is based on classical PC plus A/D and D/A converters and the second one is based on a microcontroller (Atmel ARM7). Both methods can be used for verification of algorithms for control and identification of processes, modeling of transport processes dynamics using simulation experiments, if simulations run in real time. The application of a microcontroller allows a simple realization of changing parameters and also non-linearity of the process. In the paper we also pay attention to the realization of real time in a programmable environment under Microsoft Windows and the realization of precise calculations in floating point on microcontrollers.
