摘要： A phase control system has a stable timebase phase reference generated by an internal phase reference generator which has improved transient response in the presence of spurious noise generated by other external equipment coupled to the same voltage source. A digital phase comparator estimates a phase error between the timebase phase reference and the voltage source. The internal phase reference generator constructs the timebase using a normalized difference between the volt-time-areas between two adjacent quadrants of the internal timebase phase reference. This allows corrections to the phase reference generator to be made on the next cycle of the phase reference generator based on the error estimate of the present cycle.

摘要： A field bus network of input and output devices is coupled to a control system through an I/O interface module, regardless of their data structures. The I/O interface module is coupled to the control systemthrough a serial communication port. Local input and output devices are coupled to the interface I/O module through a local I/O interface and networked input and output devices are coupled to the interface I/O module through a field bus communication adapter. A different adapter is required for each type of field bus protocol. The interface I/O module includes a microprocessor based device to generate and control the various interactions between the local devices, networked devices, and the controllsystem and also to provide for a visual and status display of the fieldbus and local I/O data local.

摘要： A phase controlled weld controller system provides a stable timebase phase reference which has improved transient response in the presence of spurious noise generated by other external equipment coupled to the same voltage source. The system estimates a phase error between an internal phase reference generator and the voltage source. The system also estimates the phase distortion generated by the weld control when operating with an inductive impedance load when significant line impedance is present. The weld controller provides compensation for the phase distortion in the timebase phase reference using the estimated line impedance to realize a phase reference which more accurately tracks the voltage source.

摘要： A phase controlled weld controller system uses an internal model of weld line and load impedance and of open circuit weld input voltage to develop a nominal firing angle sequence to maintain a desired weld current sequence. The weld controller computes a nominal firing angle sequence based on estimated models of line impedance, open circuit line voltage, and an estimated relation between the load current and conduction angle and the mathematical relation between firing angle, conduction angle and load circuit power that will achieve a desired weld sequence if the models are accurate. The weld controller subsequently uses measured values received in real time while the weld sequence is being executed to modify the nominal firing angle to better achieve the desired objective. This approach allows the weld controller to quickly achieve the desired weld sequence with the actual load, while permitting low feedback gains, resulting in a system that is quick and accurate in response without being overly sensitive.

摘要： A weld controller maintains an internal dynamic model of load impedance, which tracks normal impedance variations that occur as the weld tooling degrades. The weld controller contains a weld process monitor function that tests an estimated load impedance of a weld schedule presently under execution against an internal dynamic model and generates events when characteristics of the estimated load impedance of the present weld falls outside an operator definable band, indicating a problem with the workpiece presently being welded. The weld controller further includes the capability to accept a static model of the load impedance that is used as the reference impedance for the weld control and tooling. The weld controller also includes means to declare an event when characteristics of the dynamic model differ from the static model by an operator-defined amount. The weld controller allows a distinction to be made between a short-term difference in load impedance, generally indicative of a weld process variation and the long-term difference in load impedance, generally indicative of tooling degradation. This provides for tighter controls of weld process variations than could previously be achieved, coupled with an indication of incipient tooling faults.

摘要： A phase control system has a stable timebase phase reference generated by an internal phase reference generator. The control includes a method for estimating and compensating phase distortion when an inductive load is driven by an AC voltage source having significant line impedance. A digital phase comparator estimates a phase error between the timebase phase reference and the voltage source. At the initialization of the phase control system, the phase reference clock period is frozen for a fixed number of cycles to determine an average phase error due to the phase distortion caused by the line impedance. The estimated phase error is then corrected to account for the average phase distortion error.

摘要： Power measurement by tracking of a voltage cycle when voltage and current measurements are taken at different locations on an AC power line, with the devices taking the measurements interconnected by an asynchronous data network. In general, a synchronization/timing message is sent from the voltage sensing side to the current sensing side, with the synchronization/timing message being transmitted at a predetermined point in the periodic voltage cycle. The receipt of the synchronization/timing message by the current sensing side may be used to re-synchronize an internal model of the voltage cycle maintained by the current sensing side to the measured voltage cycle. The predetermined point in the voltage cycle may be the zero-crossing point, or other point, of the voltage cycle.

摘要： A series of remote input/output repeater modules connected on a synchronous serial communication network supervised by a programmable logic controller uses a synchronous serial communications protocol. The programmable logic controller contains a transmitter module for generating a data packet containing the state of output devices connected to the remote input/output repeater modules. A receiver module receives and decodes a returned modified data packet that indicates the state of input devices connected to the same or other remote input/output repeater modules. The remote input/output repeater modules receive and decode the data packet to determine the state of the output devices that may be connected to it and modifies the data packet to indicate the state of its input device if there is one present. The modified data packet is sent to the next in-line remote input/output repeater module coupled to the network.
