Automated Loop Tuning

Jan. 1, 2006
As a new adaptive control option for the PPC-2000 programmable multi-loop process control system, Tru-Tune is designed to help fine-tune PID control loops and adaptively tunes dynamic systems that would otherwise have to be re-tuned by operators.

The Tru-Tune option improves tuning by automatically optimizing control parameters whenever necessary to keep the system at target temperature. When a system is well-tuned, the product is kept closer to the ideal processing temperature. This improves yield and reduces scrap and the need for reworking misprocessed material. The PPC-2000’s standard firmware option controls up to 48 PID loops. The Tru-Tune option offers 32 loops of PID control with up to eight adaptively tuned loops.
