Operating Instructions Temperature Indicating Controller CF1H 8. Control actions 8.1 Fuzzy self-tuning Fuzzy self-tuning is a function to perform a fine adjustment of PID values automatically. The stable control can be carried out even if the conditions of the process are changed due to things like change in types and rates of production. (1) When the control is rising, the controller performs the control by the PID values tuned in advance.
Operating Instructions Temperature Indicating Controller CF1H 8.2 Explanations of PID (1) Proportional band (P) Proportional action is the action which the control output varies in proportion to the deviation between the setting value and the processing temperature. If the proportional band is narrowed, even if the output changes by a slight variation of the processing temperature, better control results can be obtained as the offset decreases.
Operating Instructions Temperature Indicating Controller CF1H 8.3 PID auto-tuning of this controller In order to decide each value of P, I, D and ARW automatically, this system gives the fluctuation to the controlling object by force.
