A new approach of a Numerical Methods Controller for self-regulating processes

Abstract:

The aim of this paper is to design a Numerical Methods Controller (NMCr) based on a first order plus dead time (FOPDT) model of the actual process. The overall idea is to develop a general NMCr, which can be used for different self-regulating industrial processes, if they have a similar open loop response, such as an FOPDT model. Hence, this work summarises the easily and simplicity of numerical methods procedures along to a reduced order model of the process to obtain a simple and versatile controller. The performance of the proposed controller in this article is tested by simulations in several higher order linear systems with different characteristics. It is compared against a PID, and also its robustness is checked.
