Methods and systems for creating and running and industrial control system simulation are described herein. The simulation may include animation of a complex machine linked with the industrial control device controlling the complex machine. The simulation may also include links to the physical I/O and other modules of the industrial controller to enhance the functionality of the simulation. This may increase the likelihood that the timing and functionality of the simulation may be more like real-time operation of the industrial control system. This may enhance the system design and save time of system design and start-up and troubleshooting of the operational industrial control system.

A distributed machining simulation partitions a model of the workpiece to produce a set of sub-workpieces and modifies the machining instructions for each sub-workpiece to produce a set of groups of modified machining instructions different from the machining instructions. Each group of the modified machining instructions is associated with a sub-workpiece and includes effective machining instructions that move the machining tool through the sub-workpiece and at least one fake machining instruction that moves the machining tool through the model of the workpiece outside of the sub-workpiece. The distributed machining simulation remote hosts to simulate the machining of the workpiece using at least one group of the modified machining instructions to produce geometries of a machining simulation of the workpiece, each geometry is associated with a corresponding sub-workpiece and reconstructs a representation of the machined workpiece using a portion of each geometry within the volume of the corresponding sub-workpiece.

One of the curves includes a point on the curve indicative of a lowest amount of energy consumed for a desired production rate range.

A system for path command generation includes an industrial machine, an interface accessible via a remote device, and a server communicably coupled to the industrial machine and the remote device via a network. The server includes processing circuitry configured to calculate an optimum path command, simulate the optimum path command based on the calculation of the optimum path command, calculate a cycle time and error of the path command, determine if the path command is acceptable, and transmit path command data to the industrial machine in response to the acceptable path command being selected.

An information processing device controls operation trouble or a calculation amount related to a machine interference check by automatically creating a three-dimensional model optimal for the machine interference check. The information processing device optimizes, for the interference check, three-dimensional model data of a machine including a plurality of structures. The information processing device includes a check object selection unit that performs selection among the structures, and a model creating unit that creates three-dimensional model data for an interference check which data includes the selected structure. Since the information processing device can generate three-dimensional model data optimized for an interference check, there is no trouble for a user to create new three-dimensional model data by himself/herself, and a simple and effective interference check can be realized.

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.

An operation of the machine is iteratively controlled with control inputs determined from an optimization of a cost function along a prediction horizon subject to constraints on the control inputs. The optimization is performed according to the model and the cost function includes at least one parameter of the model. During at least some iterations of the control, the parameter of the model is updated resulting in updating the cost function.

A device for simulating a controlled machine or installation includes a process simulation apparatus designed to perform simulation steps that simulate a physical process of the machine or installation, and a controller simulation apparatus designed to perform simulation steps that simulate a controller of the machine or installation. The process simulation apparatus and the controller simulation apparatus exchange particular output values so as to simulate the controlled machine or installation in the respective simulation steps. The controller simulation apparatus transmits an item of information to the process simulation apparatus, which item of information describes a result time for an end of a simulation step performed by the controller simulation apparatus, while the process simulation apparatus is designed to adjust a duration of at least one of the simulation steps depending on the result time.
