Patent number: 10120349Abstract: 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.Type: GrantFiled: March 16, 2016Date of Patent: November 6, 2018Assignee: AZBIL CORPORATIONInventors: Hayato Motohashi, Atsushi Takahashi, Hirofumi Hirayama

Publication number: 20060207272Abstract: 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.Type: ApplicationFiled: March 9, 2006Publication date: September 21, 2006Applicant: YAMATAKE CORPORATIONInventors: Hirofumi Hirayama, Fumihiro Sugawara
