A study on controller design strategies for tito plant
The work studies on the performance of diagonal and multivariable PI control strategies applied to two-input two-output (TITO) nonlinear wastewater treatment plant (WWTP). WWTP is highly known with the variation and uncertainty of the parameters, making them a challenge to be controlled. Thus, simpl...

| Summary: | The work studies on the performance of diagonal and multivariable PI control strategies applied to two-input two-output (TITO) nonlinear wastewater treatment plant (WWTP). WWTP is highly known with the variation and uncertainty of the parameters, making them a challenge to be controlled. Thus, simpler control strategies are always demanded. An adaptive interaction algorithm is used in tuning the diagonal PI controller while Davison and Penttinen-Koivo methods are applied in multivariable PI controller. It was observed that the simulated diagonal PI controller perform well in tracking the substrate and dissolve oxygen concentrations while the disturbances are well compensated by multivariable PI controllers. |
