Adaptive Decoupling Control of Three – Tank – System
Adaptive control of a three – tank - system laboratory model is presented. The objective laboratory model is a two input – two output (TITO) nonlinear system with internal interactions between input and output variables. It is based on experience with authentic industrial control applications. Two control algorithms based on polynomial theory and pole – placement are proposed. Decoupling compensators are used to suppress interactions between control loops. The algorithms implemented as self – tuning controllers are then used for control of the model. Results of real-time experiments are also included.
