Abstract

Concept of control. Modelling of dynamical systems. State space description, linearisation. Laplace transform, system response. Closed loop control - idea of feedback. PID control. Stability, Routh-Hurwitz criterion, frequency response, Bode diagram. Feedforward compensation, cascade control. Multivariable systems. Applications to distillation and reactor control.

Objective

Chemical Process Control. Process automation, concept of control. Modelling of dynamical systems - examples. State space description, linearisation, analytical/numerical solution. Laplace transform, system response for first and second order systems. Closed loop control - idea of feedback. PID control, Ziegler - Nichols tuning. Stability, Routh-Hurwitz criteria, root locus, frequency response, Bode diagram, Nyquist criterion. Feedforward compensation, cascade control. Multivariable systems (transfer matrix, state space representation), multi-loop control, problem of coupling, Relative Gain Array, decoupling, sensitivity to model uncertainty. Applications to distillation and reactor control.
