Perbandingan Kinerja Sistem Kontrol Berumpan Balik Feedback dengan Sistem Kontrol Berumpan Maju Feedfoward pada Jaringan Penukar Panas Heat Exchanger

摘要

In industrial process, there are many variables that must be controlled. Control Action can be done manually by operator, but because in industrial process contains hundred of variables that must be controlled, so the consequence is hundred of operators are needed. Therefore the best way is applied automatic s control in industrial process. Process heat is used for many various applications. Temperatures depend on industry type, such as high heat up to 1500 oC. Chemical industry is an example of industry with temperature range between 500-600oC. Non-iron metal industry, and hydrogen production are applications that use temperature range between 600 - 1000oC This paper explained about the comparison between feedfoward and feedback control system on heat exchanger plant. After mathematical models can be obtained, the next step was to simulate system performance by using Matlab. From the simulation result, was obtained that every control strategy had its strength and weaknesses. So their combination will give better response.
