AUTOMATICALLY EVOLVING A PROCESS MODEL
Methods are provided of automatically evolving a process model including process-elements and relationships between process-elements. The method comprises receiving user input defining one or more new constraints to be satisfied by the evolved process model. The method further comprises performing an optimization method to find a best solution of a cost function depending on a set of optimization conditions, over a solution space of possible consistent and/or sound process models derivable from the process model to be evolved depending on the one or more new constraints. The set of optimization conditions comprises maximization of constraints satisfaction corresponding to satisfaction of the one or more new constraints and of previous constrains from previous executions of the method. The method still further comprises updating the process model with the obtained best solution. Computer programs and systems are also provided that are suitable for performing such methods.
Modeling of an industrial automation environment in the cloud
A cloud-based modeler component that generates interactive models of an industrial automation system(s) (IAS(s)) is presented. An interactive model facilitates remote viewing of, interaction with, troubleshooting of problems with, or optimization of industrial assets of an IAS. The modeler component polls industrial assets via cloud gateways to obtain information relating to the industrial assets to identify industrial assets of the IAS and relationships with other industrial assets or can receive information from a communication device that obtains information relating to legacy industrial assets to identify those legacy assets and their relationships. The modeler component generates an interactive model of the industrial assets of the IAS based on the information. The modeler component also can discover new industrial assets added to the IAS, can receive a pre-deployed model of an industrial asset from the industrial asset or another source, and can incorporate the pre-deployed model in the interactive model.
Method and apparatus for evaluating and selecting signal comparison metrics
A method for evaluating a simulation model. In the method, for selected test cases, a first performance index is calculated in the simulation model. For the same test case, a second performance index is ascertained in a real test environment. For each of the test cases, a difference is calculated between the first performance index and the second performance index, and a signal metric is determined. For each of the signal metrics, an interrelation between the difference and the respective signal metric is investigated. The signal metric that exhibits the closest interrelation with the difference is selected.

Method and apparatus for online simulation of complex motion systems
A system and method for online simulation of a controlled machine or process utilizes a simplified model of the system dynamics and may be used with hardware in the loop to evaluate performance of the controlled system or with software in the loop to perform commissioning of the control program prior to completion of the mechanical installation. The simplified model includes dominant order dynamics of the controlled system such as the inertia of the system and a damping factor. Further, the online simulation is scheduled to execute at an update rate slower than the update rate of the control loops within the motor drive. The simplified model and reduced update rate reduce the computational burden on the processor such that the simulation may be performed either on the industrial controller or on the motor drive.
