Abstract:
A motion control design system implements a performance specification-oriented design approach. The system allows a designer to define desired performance specifications that are to be satisfied by a motion system, and determines tuning parameters (e.g., controller bandwidth and associated tuning parameters) that will yield performance within the defined performance specifications. An identification process identifies system parameters of interest based on collected system data. After the user has entered the desired performance specifications, an optimization process determines a range of bandwidths that will satisfy all specified performance requirements, and selects an optimal bandwidth within this range. A tuning process generates the corresponding tuning parameters for a systematically designed motion controller. Rather than using an optimal solver, the design system stores relationships between performance specifications and the major tuning parameter as matrices or mapping functions, given system parameters as inputs, making the design system suitable for embedded systems.
Abstract:
A motion controller device and a communication method for the motion controller device are provided to reduce the large number of man-hours that are required for making communication settings and wiring design in large-scale systems. The motion controller device and communication method improve the degree of freedom for communication line connections by switching the two transmission paths on the transmitting and receiving sides of the communication ports contained within a central communication device and a terminal communication devices for full duplex communications. The motion controller device and communication also ensure the response performance required in the devices being controlled by way of the terminal communication device that autonomously and dynamically switches the communication paths according to the volume of communication data on the communication line along this type of network.
Abstract:
The claimed subject matter provides systems and/or methods that facilitate utilizing a motion control timing model to coordinate operations associated with controlling motion within an industrial automation environment. For example, a cycle timing component can implement timing set forth by a timing model (e.g., that can be selected, preset, . . . ). Pursuant to an illustration, the cycle timing component can utilize the timing model to coordinate transmitting data, receiving data, performing calculations associated with data (e.g., to generate command(s)), capturing data, applying received commands, and so forth.

The invention includes: a numerical controller for controlling a servo amplifier in accordance with a given motion command; a memory for storing as variables motion command data such as speeds and positions; a motion API which is called by an application program on a personal computer and which gives a motion command via a bus such as a PCI bus to the numerical controller; and means for indirectly specifying the address of a variable of motion command data present in the memory by way of the motion API.
Abstract:
A system for motion control in which an application is developed that is independent from the actual motion control hardware used to implement the system. The system comprises a software system that employs an application programming interface comprising component functions and a service provider interface comprising driver functions. A system programmer writes an application that calls the component functions. Code associated with the component functions relates these functions to the driver functions. A hardware designer writes driver code that implements the driver functions on a given motion control hardware product. The driver functions are separated into core and extended driver functions. All software drivers implement the core driver functions, while the software drivers need not contain code for implementing the extended driver functions. If the software driver does not contain code to implement an extended driver function, the functionality of the extended driver function is obtained through a combination of core driver functions. The system programmer may also select one or more streams that allow the control commands to be communicated to, and response data to be communicated from, motion control hardware.
Abstract:
A system for allowing an application program to communicate with any one of a group of supported hardware devices comprising a software system operating on at least one workstation and a network communications protocol. The software system includes a control command generating module for generating control commands based on component functions of an application program, component code associated with the component functions, and the driver code associated with software drivers associated with the hardware devices. The network communication protocol allows the control commands to be communicated from the control command generating module to at least one of the supported hardware devices over the network.
Abstract:
A system and method for facilitating communication between an application program and underlying motion control hardware in a hardware independent manner. A communication map maps a generic grid of mapping information cells to the actual information cells implemented by the particular hardware. Each actual information cell may be located in different areas and may transfer different values on each hardware platform. The communication map allows common functions to be used across a plurality of supported hardware device implementations.

Abstract:
A control system for controlling displacement of a member in a glassware forming machine. A pneumatic piston drives the member and is controlled by a computer which defines a motion profile. The difference, at any moment, between the demanded position and the actual position is determined and an error signal is defined based on the difference signal and the momentary velocity and acceleration.
Abstract:
An industrial control system provides for distributed processing of position related signals by remote I/O modules to correct for spatial offsets of sensors or actuators associated with the I/O modules, the latter which may receive position data and may correct timing signals detected at the I/O modules according to a stored position offset within the I/O modules.
