The mixing process is a multivariable and intrinsically non-linear plant. Mathematical modelling of the mixing color process has been taken into consideration in order to design an adequate control (PI controllers) to assure zero steady state, fast control and disturbance rejection. The comparisons of the nonlinear mathematical model and linear one have been done. The control of the process has been...
Computational fluid dynamics (CFD) software FLUENT 6.3 has been employed in the present work to study the flow field and mixing process in a stirred tank equipped with four side-entering agitators. The multi-reference frame (MRF) and standard k-ε turbulent model were used in the simulation. The effects of tracer feeding, detecting positions and impeller speeds on mixing time were investigated. It...
Offline optimization of controller parameters for complex non-linear processes can be time consuming, even with high performance computers. This project demonstrates how Metamodeling techniques can be utilized to tune the controller parameters for a non-linear process quickly. The process used in this study is the mixing process which is a multivariable and intrinsically non-linear plant. The Radial...
