Abstract
The optimization and fine control of industrial process are important to improve the productivity, quality and reducing costs, considering the safety of factories and the competitiveness. The simulation processes are useful to anticipate the results of production systems used in industrial sites and to develop high fidelity control systems. The objective of this study was to find the transfer function of a light sensor (model LDR) and compare the results of this empirical equation simulated in Scilab with real results of the sensor in serial with a first order system. It was used a first order system as base to construct the empirical equation based on changes in the time constant (Tau). After collection of the data with the sensor, "Tau" was changed from 0.00001 seconds to 0.1 seconds. The results shown that 0.01 seconds is the best value to represent the light sensor. It is suggested to develop another analysis with different measuring systems to find empirical transfer functions to create a databank of these instruments on Scilab to develop systems modelling for engineered applications.
