Multivariable model predictive controller

Model No.

SORTiA-MPC is a multivariable model predictive control package that lies at the core of SORTiA.

SORTiA-MPC provides multivariable model predictive control technology as the core software component of SORTiA.


SORTiA-MPC stabilizes and optimizes operations in continuous processes, resulting in stable product quality, improved recovery rates and consumption rates, and energy savings.

Easy to use

The main feature of this software is multivariable model predictive control, which provides three degrees of freedom, allowing fully independent adjustment of optimization speed, feed-back strength, and feed-forward strength.

Thanks to this feature, the software can make adjustments according to the characteristics of the equipment. For example, optimized speed can be kept at a reasonable value and feed-forward control for observation disturbance enhanced while maintaining robustness, so the system can easily cope even in cases where there are large modeling errors.

Functions based on on-site experiences

Developers of SORTiA-MPC include engineers who have been involved in process control for many years. So this software includes control functions developed based on on-site experience and knowledge of important points when applying the multivariable model predictive control applications such as:

  • Handling methods for processes with very high interference
  • Handling methods when there are both quick and slow responding variables
  • Control of integral processes

The control functions incorporate our experience and knowledge gained in the field, which is essential when applying multivariable model predictive control in situations such as the above.

Support for DCSs other than Azbil Corporation's

Use of an open system configuration not dependent on any existing DCS (distributed control system) allows use by the customers who have a DCS other than from Azbil Corporation.

Cost savings by virtualization

This software employs virtual technology to save costs on server replacement that is required every few years due to limited PC service life.

Pay-as-you-go fee system

Instead of a license fee system, which can cost several million yen per device, this software employs a pay-as-you-go yearly fee system (depending on the number of operation variables or connected users) to provide reasonable pricing starting at several hundred thousand yen depending on the scale of the device. This also serves to broaden the scope of application

Support in two languages

Users can select Japanese or English as a language to display in operation screens and messages.
