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 prototype) 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.
