METHOD AND SYSTEM FOR CONTROL AND CO-SIMULATION OF PHYSICAL SYSTEMS

摘要

A method for control and co-simulation in a system having multiple subsystems, each representing a physical system, includes, in a first subsystem simulating a first physical system, providing a first time continuous output signal representing a property of the first physical system, and filtering the output signal using a continuous moving average (CMA) filter as an anti-aliasing filter to form a filtered time continuous signal. Filtering the output signal includes integrating the time continuous signal to form an integrated signal, sampling the integrated signal, for each sample, forming an average value from the current sample and a previous sample, and forming a filtered time continuous signal from the average values. The method also includes providing the filtered time continuous signal to a second subsystem simulating a second physical system. A system for performing the method is also provided.

1. A method for control and co-simulation in a system comprising a plurality of subsystems, each subsystem representing a physical system, the method comprising:
in a first subsystem simulating a first physical system, providing a first time continuous output signal representing a property of the first physical system; filtering the output signal using a continuous moving average filter as an anti-aliasing filter to form a filtered time continuous signal, wherein filtering the output signal comprises integrating the time continuous signal to form an integrated signal, sampling the integrated signal, for each sample, forming an average value from the current sample S0 and a previous sample S0-n, where n>0, divided by total sample time h*n, where h is sample period, and forming a filtered time continuous signal from the average values; and providing the filtered time continuous signal to a second subsystem simulating a second physical system.
