In order to deal with plant-model mismatch, real-time optimization schemes use some adaptation strategy based on measurements. The modifier-adaptation approach has the ability to converge to the true process optimum but it requires the experimental estimation of the process gradients. Dual modifier-adaptation algorithms estimate the gradients based on the current and past operating points. This paper presents a new dual modifier-adaptation approach. The approach is compared with a previous approach found in the literature showing faster convergence to a neighborhood of the plant optimum.
