The Given

AbstractModelling and controlling of Continuous stirred tank reactor (CSTR) is one of the major problems in the process industry. The nonlinear characteristic of CSTR may change the variation of temperature in either direction from the given set value. Chemical reactions within the CSTR depends on the given reference temperature. Such variation from reference values may result in degrading the variety of biomass. Design and implementation of the precise control device in such system are difficult for researchers. This paper proposes the MIT based control scheme as a solution to control problem of CSTR. An improvement of signal synthesis MIT system has been proposed in this study to enhance the steady-state and transient performance of CSTR. Artificial Bee Colony (ABC) based controller parameter tuning technique is applied to get the optimal performance of the controller. This paper shows the design and implementation of conventional PID tuned with the Z-N method, adaptive PID tune with ABC, MIT and ABC-MIT for CSTR. Detailed comparison based on simulation studies is presented which shows that ABC-MIT based control scheme improves the transient and steady state response.

Continuous Stirred Tank Reactor (CSTR) atau Reaktor Alir Tangki Berpengaduk(RATB) merupakan salah satu jenis reaktor yang umumnya berbentuk bejana danbekerja secara kontinyu. Continuous Stirred Tank Reactor (CSTR) banyakdigunakan untuk reaksi-reaksi homogen fase cair tanpa katalis maupun dengankatalis. Penelitian ini bertujuan untuk mendapatkan respon terbaik kontrol PIDdengan menggunakan metode trial and error pada nilai Kc, Ti, dan Td. Metodetrial and error adalah adalah metode mencari nilai parameter dengan caramencoba-coba suatu nilai tertentu sebagai parameter sampai didapat sebuahperformansi kontrol PID yang terbaik. Sistem kontrol PID merupakan controlleruntuk menentukan presisi suatu sistem instrumentasi dengan karakteristik adanyaumpan balik pada sistem tersebut (Feed back). Adapun metodologi penelitian iniadalah membuat model steady state Continuous Stirred Tank Reactor (CSTR),kemudian mengubah model steady state menjadi model dynamic, lalu membuatmodel kontrol PID, setelah itu melakukan tuning terhadap kontrol PID danmelakukan pengujian terhadap kontrol PID, dengan melakukan gangguan padaset point. Nilai Kc = 8, Ti = 1 dan Td = 0 respon waktu rata-ratanya 0,815 menit, sebuah sistem pengendalian suhu yang dapat diterapkan untuk mendapatkanwaktu yang paling optimal. Nilai Kc = 10, Ti = 4 dan Td = 0 waktu rata-ratanya1,257 menit sebuah sistem pengendalian suhu yang memiliki waktu yang kurangoptimal. Kata Kunci: Continuous Stirred Tank Reactor (CSTR), PID, Set Point.
