Long Range Predictive Optimal Control Law with Guaranteed Stability for Process Control Applications

The Generalized predictive Control law has been successfully applied in industrial applications but has limitations on non-minimum phase processes for some of the most obvious choices of cost-functions. The Weighted Predictive Control law proposed here is new and avoids these difficulties whilst maintaining a similar philosophy. It ensures guaranteed stability when the control weighting tends to zero, even if the system is non-minimum phase.
