Most
industrial control loops are still of PID types. According to statistics, about
50% of the industrial PID loops are poorly tuned, which greatly hinders the
operation of production units. Therefore, optimization of PID parameters will
improve production unit operation and bring huge economic benefit.
Much
PID tuning work is done manually, which is time consuming and tuning quality
cannot always be guaranteed. Currently, most PID tuning packages use open loop
step test for model identification. This will disturb unit operation.
Tai-Ji
PID is a PID tuning package based on closed-loop identification:
·
Obtains
models using closed-loop identification
·
Closed-loop
test do not disturb unit operation
·
Highly
efficient, can test and tune 10 loops simultaneously
·
Tuning
cascade loops using one test
·
Using
multivariable models to tune interactive loops and to provide decoupling
parameters (next release)
·
User-friendly,
designed for layman of PID control
·
Connects to
DCS and PLC using OPC
·
Compatible
with many systems: Honeywell, Foxboro, Bailey, Yokogawa, DeltaV, Siemens and
more...
