Linearization of a MIMO process using LabVIEW

Abstract

The processes encountered in the real world are usually multiple input multiple output systems (MIMO). The interacting level process is described in this paper. The output of the level process is non-linear and it is converted into the linear form by using Taylor Series method. By using Taylor series method in the non-linear equation, the converted linear equation for the MIMO process is obtained. The aim of the process is to keep the liquid levels in both the tanks at the desired values. The LabVIEW software is used to simulate the system. The simulated results validate the method applied here.
