Control Functions On-Off Control Fuzzy Control with Auto Tuning Simple and Basic Control Suppresses Overshoot by Fuzzy Calculation When process value (PV) is below the set value (SV), PXF turns on the output to energize the heater, and vice versa. In this way, PXF keeps the temperature constant by turning the output on and off based on the SV as a threshold. Without fuzzy control Fuzzy control Self Tuning Control For Changing Temperature PID Control with Auto Tuning Typical Control Based on PID Theory The controller calculates optimal PID parameters. There are 2 types of auto-tuning functions;...

Functions for better user experience Simple Program Control (Ramp Soak Function) PXF automatically changes SV to the preset values at preset times. You can set up to 64 steps and 15 types of operation patterns. For example, when you bake four kinds of bread, you can divide 64 steps into four patterns to set suitable temperature for each bread. You can start/stop/suspend the operation using a user key, parameter setting, digital input, or communication.

Auto-Tuned Fuzzy Control PXR monitors the process temperature and suppress overshoot and effect of external disturbances based on the fuzzy logic, without increasing the startup time. Fuzzy control Without fuzzy control The controller tunes PID parameters when necessary; for example, at startup of the equipment, when the setpoint is changed, and/or the process temperature changed due to disturbance. External disturbance Set value change Note: For some objects to control, PID values could not be optimized.
