Accurate and robust models of a mechanism are required for the design and parameter optimization of control system algorithms, as well as their reliability verification (mechatronics simulation). RecurDyn provides a diverse set of tools to analyze mechanism models coupled with the control system algorithm.
RecurDyn provides a special interface for co-simulation with the MATLAB/Simulink that is widely used for mechatronics simulation. In addition, RecurDyn supports FMI to incorporate the use of AMESim and Modelica-based applications.
RecurDyn/CoLink allows for fast and accurate control system analysis through the deep integration of the control simulation code with RecurDyn’s dynamics solver.
Matlab/Simulink
RecurDyn/Control includes an interface for co-simulation with MATLAB/Simulink.
This allows mechanical systems that contain control and drive systems, such as controllers and motors, to be analyzed using mechatronics simulation.
Simulink Interface:
- RecurDyn/Control includes an interface which allows it to utilize a realistic dynamic model of RecurDyn in a MATLAB/Simulink model.
- It is possible to use a RecurDyn model including contacts or flexible bodies as well as various joints or forces in the model created by Simulink.
- A RecurDyn model can be integrated with a Simulink model using a UI which easily creates an S-Function for the RecurDyn Plant model.
FMI (Functional Mockup Interface)
RecurDyn supports FMI, a standard interface based on Modelica, and co-simulation with applications that support FMI
Support for co-simulation with AMESim, SimulationX and Simplorer
Benefits
- Controls engineers can efficiently test control algorithms early in the design process with highly nonlinear dynamic models for mechatronics simulation.
- 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.
