Abstract |
|
Conventional PI controller is the simplest well known controller used in utmost of the process. The main reason behind its popularity among engineers is its simplicity in tuning the parameters to achieve satisfactory performance in industrial applications. It fuses the properties of the P and I controller and it shows maximum overshoot. They are widely used because of their robustness, simplicity and successful practical application. In this process we are going to control the level of the tank using non-linear spherical tank. Here we are implementing using classical methods as well as T-L method. The system identification of the non-linear process is found by first order plus dead time model (FOPTD). The ability of the designed controller, in terms of tracking set point, is also compared and simulation results are produced. |
