ADAPTIVE CONTROL OF THREE - TANK - SYSTEM: POLYNOMIAL APPROACH

Control of a three – tank - system laboratory model as a two inputs – two outputs system is presented. The objective laboratory model is a multivariable nonlinear system. It is based on experience with authentic industrial control applications. Two control algorithms utilizing polynomial theory and pole – placement are proposed. Particular controllers are based on various configuration of the closed loop. The algorithms in adaptive version are then used for control of the model. The results of the real-time experiments are also included. Quality of control achieved by both methods is compared and discussed.
