RAMIREZ, R.  e  AGUADO, A.. Control of a biomass combustor using the general Smith Predictor. J. appl. res. technol [online]. 2003, vol.1, n.1, pp.53-62. ISSN 2448-6736.

This paper proposes a modification to the classic Smith Predictor, known since several decades as an effective control method for the pure delay noxious effect in the control loop systems. The modification consists in the use of a high order model for the system, using an idea of Strejc, instead of the first order model with delay as was proposed by Smith. This allows better approximation to high order systems. It is presented an algorithm to calculate the Strejc model of the system to be controlled, based on its response to a unit step disturb.
