摘要： An acceleration and deceleration controlling apparatus in which a positional moving amount supplied from a host is converted into an accumulated value of absolute positions by two serially connected accumulators to be output to a first stage of a buffer registers 4. A switch 5 is provided to read out a value from a desired register among the buffer registers 4. The switch 5 changes the substantial number of stages of the buffer registers 4. At the same time, by correspondingly switching the divisor of the divider 7, the time constant for the acceleration and deceleration are desirably changed, which contributes to optimize the acceleration and deceleration time and to reduce the processing time.

摘要： A system for monitoring a multiparameter manufacturing process by examining on a real-time basis a stream of data units, each data unit including a numerical characteristic indicative of a current state of one of the parameters of that manufacturing process and a tag identifying the parameter. The system employs an entity-relational database to group and evaluate all data units using statistical evaluation criteria, and to identify and generate signals relating to particular testpoints in the manufacturing process so that an indication of the significance of the statistical pattern and the manufacturing process parameter involved are given in such terms as to permit human evaluation of and, if necessary, manual or automatic intervention in the manufacturing process.

摘要： A programmable controller is disclosed for the purpose of controlling devices such as machine tools and other machinery, and which is often mated with a host computer numerical controller. The programmable controller is configured such that certain user-designated "fast-scan" outputs can operate at much higher speeds than non-designated "normal" outputs, thereby greatly increasing the response time and efficiency of the operations that are controlled by those fast-scan outputs. The programmable controller uses a processor which scans through its user-definable program (including the value of all system inputs and outputs) before it attempts to change the value of any of its outputs. The physical input/output (I/O) interfaces are located on I/O racks, each of which also includes an intelligent bus adaptor. The intelligent bus adaptor includes its own processor which periodically communicates with the processor in the programmable controller. The intelligent bus adaptor's processor controls the fast-scan outputs located on that particular I/O rack within very short time intervals, and allows for a response time that is an order of magnitude faster than the response time of normal outputs of the programmable controller.

摘要： A feedback controller inputs a reference signal instructing a controlled variable output from an object operated in accordance with a control signal and a feedback signal, to calculate the control signal such that the feedback signal is equal to the reference signal, and to supply the calculated control signal to the object. The controller has a transfer function Gf, and functions to generate the following response waveform f (t) due to a disturbance. That is, a response waveform of the controlled variable at the time when the disturbance is added to the controlled object is set to f (t), a response waveform of the feedback signal in an opened loop state, such that feedback of said controlled variable is turned off, is set to p (t), a relative degree of the disturbance is set to "d", and a relative degree of the controlled object is set to "g". At the time in which the disturbance is added to the controlled object, each differential value of the response waveform f (t) up to at least a degree (2g+d-2) is equal to each differential value corresponding to the response waveform p (t), and at finite time, each differential value of the response waveform f (t) up to at least a degree (2g+d-2) becomes zero and after the finite time, the differential values relative to all degrees become zero.

摘要： An improved setpoint control system is disclosed for use in conjunction with process control equipment. The system generates signals representing a statistical characteristic of batches, or subgroups, of monitored values of a controlled variable. From these statistical characteristic signals, the system generates an optimum setpoint signal as a sum of a specification limit and a scaled value of the standard deviation of averages of each of a plurality of batches controlled variable values.

摘要： Method and apparatus for closed-loop control of a variable in which an analog manipulated signal is produced for discrete time intervals in response to an error signal. The effect of the manipulated signal is confined to a predetermined manipulating range. The response to the error signal is distributed among a plurality of subsequent discrete time intervals when it tends to exceed the manipulating range of the control, so that the entire rate action becomes effective. The control according to the invention allows to deal with delays up to the third order with high accuracy and extraordinary speed. Special correcting means allow to apply this type of control also to line-commutated converters and choppers.

摘要： An electrohydraulic servo system in which a microprocessor-based controller directs a pulse width modulated control signal to a servo valve for controlling flow of hydraulic fluid therethrough. Duration of each half-cycle in the pulse width modulated control signal is separately controlled by selectively incrementing or decrementing duration of the half-cycle in increments of the microprocessor clock period. Signal transition is controlled by a timer interrupt in which time required to enter the interrupt routine is measured following generation of the interrupt, and further operation is delayed by a complementary time, so that control signal transition takes place a fixed preselected number of clock periods after generation of a timer interrupt. In this way, timer interrupt latency is eliminated, and resolution of the pulse width modulated signal is enhanced through individual duration control of the signal half-cycles while maintaining a fixed modulated signal period.
