چکیده
|
Distillation control is a challenging undertaking given the inherent nonlinearity of the process, severe coupling present for dual-composition control and the sensitivity of disturbances. among various distillation operations, management of the high-purity column poses a difficult control situation due to a number of characteristics of these systems, including strong directionality, ill-conditioning and strongly nonlinear behaviour. in this paper, a diagonal pid controller is designed and analysed for ahigh-purity distillation column by computing the structured singular value μ introduced by doyle (1982). for this purpose, a structured uncertainty model has been developed which describes the dynamics of the column for the entire operating range. the achievable manageable performance is also defined in terms of the hf-norm of the weighted sensitivity function.
