Multi-loop controller with adaptive control option for optimal system tuning

December 12, 2005
TRU-TUNE™, a new adaptive control option, has been added to the company’s PPC-2000 multi-loop controller. This new option helps 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 the target temperature. When a system is well-tuned, the product is kept closer to the ideal processing temperature. This improves yield and reduces wasteful scrap and the need for reworking miss-processed material. Also, when the process variable tracks the set point more accurately, the process or equipment spends less time warming up and stabilizing, and is more available and productive, which can save capital and energy costs. The PPC-2000 is a powerful, programmable multi-loop process control system. It combines easy-to-setup, multi-loop process control and programmable logic control into one, integrated package. Its modular design lets users select a set of hardware and develop a logic program based on specific control loop and logic needs, making it ideal for OEMs, system integrators and end users. The PPC-2000 carries the CE mark and is UL® and C-UL® listed.
