the Root least square method with forgetting factor for implementation in MATLAB i have an ARX model for parameter estimation. How to calculate the P(0) for this method ?
Maybe looking at a some case study examples of application can be found of some help for those interested at the recursive least squares (RLS) algorithm ― Years ago, I have studied energetic optimization and adaptive control of dissolved oxygen concentration in aerobic fermenters. I was able to estimate (on real-time) the parameters of the usual KLa correlation through RLS with forgetting factor (RLS-FF). That correlation was logarithmic linearized to allow for RLS implementation. To improve performance, a small sinusoidal disturbance was imposed to stirring rate and/or air flow (manipulated variables).
