A method of providing stable communication between subsystems in a co-simulation system, including providing a signal Sdescribing an output angular velocity of a rotating body of the first physical system; filtering the signal Susing a continuous moving average, CMA, filter; and forming a time discrete first output signal S*. In a second subsystem the signal S* is received and the angular velocity described by S* is applied to the second physical system. A response signal S* describes a torque generated by the second subsystem. The response signal S* is received by the first subsystem where a time discrete feedback signal S* is formed based on the difference between the response signal S* and a time discrete damping signal S*.

Co-simulation system with delay compensation and method for control of co-simulation system

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.
