Typical Application of Real Time Database ESP-iSYS


{tab= overview}

Advanced process control is the core technology of computer integrated process system. And it is usually based on regulatory control in the DCS and FCS systems. It makes use of the strategies of multivariable predictive control, intelligent soft sensor and P&ID diagram to achieve the following goals: improve the control quality of complex industrial process; enhance the anti-jamming ability and robustness of the system, and thereby improve the overall benefit and competivity of the plant.

At present, the advanced process control solutions in the world are up to several thousands. The investment return period is between 6 and 10 months. It can reduce the production cost by average of 5 %. Advanced process control has been regarded as high and new technology because it requires smaller investment and yields higher benefits. It is an important measure to enhance the automation of process industries.

SUPCON has started the research, development and implementation of advanced process control technology since 1993, and released multivariable predictive control software, which was successfully applied in many industries, including petrochemical, oil refining and chemical industry. “It takes 10 years to forge a magic sword.” SUPCON successfully released the APC-Suite series software in 2003, which integrated advanced process control software platform, robust multivariable predictive control, intelligent soft measurement and technical computing. SUPCON has become one of leading providers of advanced process control software and service in the world.
