Dissertation note: Project paper (Bachelor of Chemical Engineering) -- Universiti Malaysia Pahang – 2013 Abstract: The integrating process is a non-self-regulating process that its response increases or decrease gradually with time if changing in manipulated or disturbance variable. Usually, integrating process can be found in chemical process like exothermic reaction. In chemical industry that integrating process in reaction process, can cause the unexpected event in chemical plant, such as runaway reaction. The purposed of this study is to design and tuning IMC (Internal Model Control) controller for unstable process (integrating process). The internal model control is expected to overcome the dangerous situation. The standard IMC structure however could not handle the integrating process. The modification at Kaya structure is proposed. The modification is by eliminating (replacing) disturbance controller. The proposed IMC structure then simulated to 3 cases which are Integrating First-Order Plus Dead-Time (IFOPDT), Integrating Second-Order Plus Dead-Time (ISOPDT), and Integrating Third-Order Plus Dead-Time (ITOPDT). The tuning parameter of the proposed structure is determined by using Mp tuning method. The performance at the proposed IMC structure and tuning method are compared with one degree of freedom IMC (1DOF-IMC), Kaya structure units Mp-GM tuning, and IMC-based PID controller. The results show that the proposed structure and tuning method give the smallest IAE.

The integrating process is a non-self-regulating process that its response increases or decrease gradually with time if changing in manipulated or disturbance variable. Usually, integrating process can be found in chemical process like exothermic reaction. In chemical industry that integrating process in reaction process, can cause the unexpected event in chemical plant, such as runaway reaction. The purposed of this study is to design and tuning IMC (Internal Model Control) controller for unstable process (integrating process). The internal model control is expected to overcome the dangerous situation. The standard IMC structure however could not handle the integrating process. The modification at Kaya structure is proposed. The modification is by eliminating (replacing) disturbance controller. The proposed IMC structure then simulated to 3 cases which are Integrating First-Order Plus Dead-Time (IFOPDT), Integrating Second-Order Plus Dead-Time (ISOPDT), and Integrating Third-Order Plus Dead-Time (ITOPDT). The tuning parameter of the proposed structure is determined by using Mp tuning method. The performance at the proposed IMC structure and tuning method are compared with one degree of freedom IMC (1DOF-IMC), Kaya structure units Mp-GM tuning, and IMC-based PID controller. The results show that the proposed structure and tuning method give the smallest IAE.
