DELTUM Model-less Multivariable Control
Contact Us!
Lin and Associates’ DELTUM is a Model-less Multivariable Control technology that is an agile and affordable advanced process control solution for many small and mid-sized applications. DELTUM applications can be deployed with lower cost, shorter schedule, and less maintenance and support requirements, than conventional model-based multivariable control technology, while delivering reliable high performance multivariable control.
Key Benefits:
- Increases APC agility, affordability and scalability
- Lower engineering, maintenance and support costs
- Easier to own and operate with local on-site resources
- Increases APC resources and capabilities
- Provides base control layer APC for critical applications
- Fills the gap between advanced regulatory control (ARC) and conventional multivariable control (MPC)
- General purpose toll suitable to a wide range of multivariable control applications
DELTUM-XMC is suitable for many multivariable applications that have historically remained “below the radar” of the high cost threshold of conventional multivariable control. XMC provides a low-cost rapid-deployment solution for such applications as heater pass balancing, distillation columns, and hydrotreater sulfur control. XMC can even capture the primary benefits in many historically complex large-matrix applications, such as crude oil distillation columns, hydrocracking reactors, and coking units.
DELTUM incorporates patented Rate-Predictive Control (RPC) as its internal control algorithm. RPC is inherently adaptive to changes in process gain, which has been a persistent vulnerability of model-based control. RPC can also be applied in single-loop applications, as an alternative to PID, to address historically difficult loops, such as those with nonlinear gain, dead-time, or inverse response.
Additional Features:
- Scalable and suitable for many historically “below the radar” applications
- Incorporates patented Rate-Predictive Control (RPC)
- RPC can be applied to demanding single-loop control applications
