Maybe looking at a examples of application can be found of some help for those interested on applying the recursive least squares (RLS) algorithm ― I have studied energetic optimization and adaptive control of dissolved oxygen concentration in aerobic fermenters. I have shown how the parameters of the usual KLa correlation can be estimated on real-time through RLS with forgetting factor (RLS-FF). To improve convergence and stability, a sinusoidal disturbance of small amplitude was imposed to stirring rate and/or air flow (manipulated variables):
