7 functions (1) fuzzy feedback control fuzzy feedback control expresses the basic actions of pid control in fuzzy rules and has a nonlinear characteristic in order to straighten out the problem inherent to pid control (i.e., overshoot occurs when improving response or instability arises due to a change in system even when optimum pid parameters are assigned). comparison of controllability each result of fuzzy control and pid control is shown below. it is understandable that the overshoot due to a change of set value has been suppressed in fuzzy control. (4) auto-tuning pid parameters are automatically set by controller's measurement and operation. (b) low pv type remarks: (1) once auto-tuning has been made, pid parameter values are retained despite power-off operation. therefore, auto- tuning need not be repeated for the subsequent operations. (2) during auto-tuning, control output corresponds to on/off action. this may cause pv to change widely depending on process. if such a change is unallowable, auto-tuning should not be used. (3) do not use the auto-tuning function for a process having a quick response, such as pressure control, flow control, etc. (6) dual output (option) (a) standard type (2) ramp soak function (option) function to automatically change the set point value with elapsing of time, in accordance with the preset pattern, as shown below. this device allows maximum of 4 ramp soak programs. this first ramp starts at the value measured immediately before the program is executed (pv). ramp : region in which the sp changes toward the target value. soak : region in which the sp keeps unchanged at the target value. powering on can automatically trigger the program run (power-on start function), or an external contact signal can also do that.

8 pyx5,9 example of connection of heater break alarm the controller incorporates both the heating output and the cooling output for setting "cooling control cycle", "cooling proportional band" and "dead band or overlap band". (a) setting of cooling proportional band remarks: (1) pid auto-tuning is carried out only on the heating side. during auto- tuning, output on the cooling side remains turned off. after auto- tuning, both heating and cooling operations are performed according to the same pid values. (2) id set value is the same between heating and cooling sides. individual setting cannot be accepted.
