RecurDyn/Control communicates with control system software to facilitate co-simulations between control systems and mechanical systems modeled in RecurDyn. This plays an important role since design algorithms of a controller and the corresponding mechanical system (“plant”) should be evaluated simultaneously when simulating a computer-controlled system. The control system can be easily designed using control system software such as MATLAB/Simulink.

Simulink Interface:

The user can apply the realistic dynamics model created by RecurDyn in MATLAB /Simulink by the Simulink interface. The user can use the RecurDyn model which is included in not only various joints and forces but also contacts and flexible bodies in the model created by Simulink. The user can also easily integrate the RecurDyn model with the Simulink model by UI creating S-Function to the RecurDyn Plant model.

Hydraulic:

RecurDyn/Hydraulic can be applied the realistic dynamics model of RecurDyn in AMESim which is an oil pressure system analysis software. The user can use the RecurDyn model which is included in not only various joints and forces but also contacts and flexible bodies in the model created by AMESim. Also, RecurDyn/Hydraulic helps to easily integrate the RecurDyn model by UI creating the interface block easily to the RecurDyn Plant model. AMESim Supported Versions: ~ V 14.0



Benefits

Controls engineers can efficiently test control algorithms early in the design process with highly nonlinear dynamic models.
Mechanical systems may include control systems (whether electronic, hydraulic, etc.)
The mechanical engineer and the controls engineer can join their independent design models.
Controls engineers may struggle to develop robust controllers early in the design process. because of the difficulty in constructing nonlinear dynamic models within controls software.
These difficulties can be avoided by developing the mechanical model in RecurDyn and, using RecurDyn/Control to interface with the controls software.

Process

All mechanical components and constraints are modeled with RecurDyn.
The control algorithms are modeled using the control application.
RecurDyn/Control manages the co-simulation of RecurDyn and the control application.
Plant outputs are passed from RecurDyn to the control application at a constant sampling rate.
Control outputs are passed from the control application to RecurDyn at a constant sampling rate.
