This paper proposes a case study in the control of a heavy oil pyrolysis/cracking furnace with a newly extended U-model based pole placement controller (U-PPC). The major work of the paper includes: 1) establishing a control oriented nonlinear dynamic model with Naphtha cracking and thermal dynamics; 2) analysing a U-model (i.e., control oriented proto-type) representation of various popular process model sets; 3) designing the new U-PPC to enhance the control performance in pole placement and stabilisation;4)taking computational bench tests to demonstrate the control system design and performance with a user-friendly step by step procedure.
