Abstract
An averaging tank with variable filling is a nonlinear multidimensional system and can thus be considered a complex control sys-tem. General control objectives of such object include ensuring stability, zero steady state error and achieving simultaneously shortest possible settling time and minimal overshoot. The main purpose of this research work was the modelling and synthesis of three control systems for an averaging tank. In order to achieve the intended purpose, in the first step a mathematical model of the control system was derived. The model was adapted to the form required to design two out of three planned control systems by linearization and reduction of its dimensions, resulting in two system variants. A multivariable PID control system for the averaging tank was developed using optimization for tuning PID controllers. A state feedback and output feedback with integral action control (IC) system was designed using a linear-quadratic regulator (LQR) and optimization of weights. A fuzzy control system was de-signed using Mamdani inference system. The developed control systems were tested using Matlab environment. Finally, the simu-lation results for each control algorithm (and their variants) were compared and their performance was assessed, as well as the ef-fects of optimization in the case of PID and IC systems.
