  • Patent number: 10120349
    Abstract: A control device includes a timing detection unit, a setpoint path generation unit, and a control computation unit. The timing detection unit detects a timing at which an event indicating a change in a target setpoint or an event indicating application of a disturbance occurs, as a generation start timing at which generation of a path of a generation setpoint is started. The setpoint path generation unit determines the path of the generation setpoint in response to determination of the generation start timing at which generation of the path of the generation setpoint is started and outputs, in every control cycle, the generation setpoint that follows the determined path. In every control cycle, the control computation unit calculates a manipulated variable by performing control computation using a process variable and the generation setpoint as input values.

  • Publication number: 20120112727
    Abstract: A current measurement device has a rectification unit rectifying an alternating-current signal, an A/D conversion unit converting an analog signal corresponding to a signal obtained by the rectification into a digital signal, an addition unit for adding digital signals corresponding to alternating-current signals during a sampling period among the digital signals obtained by the conversion, and a current value conversion unit for converting an additional value obtained by the addition by the addition unit into a current value using a current value conversion function. The sampling period is a common multiple of the periods of alternating-current signals of 50 Hz and 60 Hz, the current values of which are to be measured.

  • Publication number: 20090248215
    Abstract: To estimate the instantaneous electric power consumption of an actuator, such as a heater, with excellent accuracy, while using an existing structure. A control device comprises a PID control calculating unit for calculating, and for outputting to the actuator, an manipulated variable MV based on a produced variable PV of an object to be controlled; and an electric power estimating unit for estimating the electric power consumption of the actuator using an electric power estimating function equation that has been set in advance, using, as input variables, the manipulated variable MV, the produced variable PV, and an electric current value CT of the electric current that flows through the actuator in response to the output of the manipulated variable MV. The electric power estimating function equation is derived in advance through multivariate analysis from actual measured data from the input variables and actual measured data for the electric power consumption of the actuator.

  • Publication number: 20060207272
    Abstract: A control apparatus used in a control system in which the cycle time of a time proportioning signal is long, for example, a temperature control system using a cooler. Even if a manipulation value MV with respect to the cooler is drastically changed along with change of a control target value SP, the activation timing of a time proportioning output section is reset with the changing timing, so that a time proportioning signal Ton is newly generated. Alternatively, with the changing timing, the time proportioning output section is reactivated to generate the deficiency of the time proportioning signal Ton according to an increasing amount of the manipulation value MV. As a result, the time proportioning signal Ton is changed with an excellent follow-up ability.
