Modeling and Simulation of a Multivariable Process Control

This paper presents a comparative survey of different multivariable techniques applied to process control. The modeling of the physical system and real time simulations are also presented using different PID structures and applied for the regulation of level and the temperature of a water reservoir control process. The structure of the multivariable control system has been implanted using LabViewreg software. This structure uses two control loops, the first for the level regulation and the second for the regulation of temperature. Five different PID controllers are included in this paper (Ziegler_Nichols, ITAE, IMC, poles placement and dual loop) and real time results are presented
