Auto-Tune Fuzzy/PID Profile Temperature Controller

The Fuzzy Logic plus PID microprocessor-based profiling controller with many segments of ramp and dwell, incorporate two bright, easy to read 4-digit LED displays, indicating process value and set point value. The Fuzzy Logic technology enables a process to reach a predetermined set point in the shortest time, with the minimum of overshoot during power-up or external load disturbance.

  • Total 9 profiles, a profile with 16, 32 or 64 segments at most
  • Each segment to be configured as a ramp or dwell(soak)
  • Fast A-D sampling rate (5 times/s)
  • After an event the process goes to run, hold, abort, manual, failure transfer, off mode, next segment or select the second PID values
  • High accuracy of 18-bit A to D input, and 15-bit D to A output
  • The fast sample rate of 200 msec
  • Fuzzy control to reach set point at the least overshooting ans less time
  • Up to three relays are configurable for event output
  • Analog retransmission of process value & set point value
  • Optional RS-485 or 232 communications
  • Programmable port for easy configuration or calibration
  • Lockout protection for security requirement
  • Bumpless transfer of safely control while sensor breaks
  • Digital filter to improve the stability of process value
  • SEL function for easy operation

Electric heating furnace industry

Vacuum furnace equipment / vacuum melting / vacuum heat treatment

A new algorithm for PID adjustment using fuzzy rules is used to adjust the PID algorithm to eliminate the PID saturation integral phenomenon when the error is large. When the error is small, the improved PID algorithm is used for adjustment and can be automatically adjusted.
