时间比例控制型的控制装置
摘要：
本发明揭示一种在时间比例信号的周期长的控制系统、例如采用冷却器的温度控制系统中使用的控制装置，在这种控制装置中即使在随着控制目标值SP的改变对上述冷却器的操作量较大变化时，也能通过在该变化时刻将时间比例输出部的启动时进行复位，重新生成时间比例信号Ton。或者在上述变化时刻，根据上述操作量MV的增加部分，相应再启动时间比例输出部，生成时间比例信号Ton不足的部分，从而跟踪良好地使时间比例信号Ton变化。
摘要（英）：

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.
