agreement
Invensys adds CTC's new ADMC technology to its portfolio of asset performance management solutions and will help HPI plants utilize previously untapped production capacity
Invensys Process Systems has announced that it has signed a sales and marketing agreement with Cutler Technology Under this agreement, Invensys Process Systems becomes a global re-seller and a certified implementer for CTC's patented Adaptive Dynamic Matrix Controller (ADMC) technology

High-performance controllers accurate to 1 msec
High-performance controllers for rack room and field-mounting offer GPS time synchronisation for SOE and TDA time stamping with up to one millisecond accuracy.
Fieldbus I/O modules are optionally redundant
Optionally redundant fieldbus I/O modules utilise redundant/fault-tolerant communications for unprecedented availability in an automation system.
This technology represents the first major development in Advanced Process Control (APC) in 30 years.
With nearly 300 advanced control, simulation, and process optimisation solutions consultants based around the world, Invensys is now the largest authorised CTC re-seller and certified implementer.
CTC's unique ADMC technology will play an important role in Invensys' asset performance management strategy by helping refineries, petrochemical plants, and other complex process plants that find themselves in a production-constrained business environment to utilise previously untapped capacity.

Accurate level measurement, variable fluid density
The Foxboro Measurements and Instruments Division of Invensys Process Systems has introduced a level transmitter that delivers accurate measurement in either open or closed tanks.
(SimSci-Esscor's well-proven Connoisseur multivariable predictive controller will remain Invensys' preferred APC solution for central station and industrial power plants.) ADMC was developed by Dr Charles Cutler, inventor of DMC (Dynamic Matrix Control) and DMCplus, the most widely used multivariable controller technology in the HPI industry.
Dr Cutler's new ADMC is the world's only Adaptive Multivariable Controller.
This technology, which has already been proven in a large-scale US refinery, utilises a unique open loop (all valve) model of the process.
This eliminates the PID (Proportional Integral Derivative) process controllers from the control hierarchy to solve many of the problems encountered with conventional APC technology in complex, interactive HPI processes.
The ADMC technology allows the controller to automatically adapt to inevitable changes in the process, improving performance and minimising support costs over time.
It also provides the ability to utilise the full range of control valves, thus permitting the controller to operate safely with valves fully open.
In many situations, the ability to maintain optimum control with the valves fully open can enable capacity-restrained plants to increase production by as much as two to three percent.
In a typical HPI plant, this can help increase bottom-line profits by hundreds of thousands of dollars per year.
Additional economic benefits can be obtained by implementing the ADMC technology in conjunction with Invensys' well-proven ROMeo optimisation solution.
In these implementations, ROMeo would establish the optimum setpoints for the ADMC controllers.
Invensys can implement these solutions in conjunction with the Foxboro I/A Series distributed control system (DCS) or any other popular DCS that might already be in place.
Under the recent agreement, Invensys is certified to implement ADMC on process units and will also provide ongoing training and other support services for ADMC implementations.
