In this paper is presented an approach of Numerical Methods Controller (NMCr) based on an empirical linear model of the processes. The controller is developed for self-regulating processes with an open loop response similar as a first order plus dead time (FOPDT) model, and can be tuned using the characteristic parameters taken from the reaction curve. The performance of the proposed controller is tested in two nonlinear chemical processes and the results are compared, by simulations, against a PID controller using the ISE performance index to measure it.
