Abstract Concept of control. Modelling of dynamic 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. Application to 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.
