The communication function of the temperature controller and indicator controller has been gradually increased and enhanced. ① The simplest signal is the ON-OFF signal. The normal value or abnormal value can be output to the higher order by “ON-OFF” signal. ...
Read More »4-11.Heating / cooling control function
■ What is heat/cool control? For example, when conducting a performance evaluation test for electronic equipment, it is necessary to control the heater and cooling mechanism simultaneously. Heating / cooling control refers to a method in which one controller operates ...
Read More »4-10.Auto tuning function / Self tuning function
In order to perform good control with a PID controller, it is necessary to set an appropriate PID constant according to the control target. Adjusting the PID constants is called “tuning”. When analog controllers were at their peak, operators tuned ...

PID operation is common for temperature controllers and indicating controllers. There is no difference in cost when using this in PI operation or in P operation alone. Then it seems like using PID control, which should get the best control ...

■ PID features It nned to eliminate the offset and make the control response faster. Use PID behavior to satisfy both. The basics PID control 1) Proportional action ( P action) that outputs a correction amount proportional to the current ...
Read More »4-7.Proportional derivative (PD) control
Differential (PD) control is used to improve control response. Unlike the integral control, the derivative control has no control ability by itself. Used in conjunction with proportional control as proportional differential control. Differential control uses the rate of change of ...
Read More »4-6.Proportional integral (PI) control
It is thought that it can be controlled well by proportional control, but in reality, there is a problem when the current value approaches the set value. That is, the amount of operation becomes too small, and it becomes impossible ...
Read More »4-5.Time proportional control, continuous proportional control, position proportional control
Proportional control is divided into three types, time proportional control, continuous proportional control, and position proportional control, depending on the heating method. ①Time proportional control (switching control) ◎ Time proportional control is a control that finely changes the ratio of ...
Read More »4-4.Proportional (P) control
In the ON-OFF control, when the heating output (operating amount) is 0% or 100%, the control result overshoots due to the effect of detection and reaction delay, and cycling is repeated. Cycling is inevitable with ON-OFF control because it performs ...
Read More »4-3.Hysteresis control
If it is turned ON and OFF at one point, the output will be chattered and will be more susceptible to noise. For this reason, as shown in the figure, heating control usually has a range of ON-OFF, such as ...
Read More »4-2.ON-OFF control
If the current temperature is lower than the set value, turn on the heater to heat. When it becomes higher than the set value, turn off the heater and cool naturally. The control method that keeps the temperature constant by ...
Read More »4-1.Glossary
Control Control is derived from the Latin contrarotulare, where contra means “to” and rotarye means “scroll”. When these are combined, the control comes from the fact that “if there is a difference, it will be corrected according to the authority ...
