Abstract
This study was devoted to limit the stability conditions of the wastewater treatment unit. LABVIEW was a powerful and versatile graphical programming language in automation control and date acquisition of the system. The on-line show that accurate and stable control responses were obtained in the present work. The actual phase plane proved to a better technique to limit the regions of the non-linear system stability compared to other theoretical techniques. Limit cycle did not appear in the present system.
