ABSTRAK

Continuous Stirred Tank Reactor CSTR merupakan suatu plant nonlinear yang banyak digunakan di industri-industri kimia sebagai pengaduk bahan-bahan kimia. Proses di dalam CSTR sangat dipengaruhi oleh suhu di mana suhu tersebut didapat dari uap panas yang mengalir di dalam dinding tangki melalui pipa sehingga suhu tersebut harus dijaga supaya tetap berada pada suhu kerja dengan merancang suatu kontroler. Suhu di dalam tangki dideteksi oleh sensor dan dari informasi pengukuran tersebut kontroler akan memberikan sinyal kontrol sehingga proses yang terjadi pada CSTR dapat kembali berjalan sesuai dengan yang diinginkan. Kesalahan pengukuran pada sensor dapat menyebabkan proses tidak berjalan dengan baik bahkan dapat mengakibatkan berhentinya proses. Fault Tolerant Control FTC kontrol toleransi kesalahan dapat memberikan kompensasi sehingga proses dapat berjalan dengan baik meskipun terjadi kesalahan pengukuran pada sensor. Pada Tugas Akhir ini dilakukan perancangan kontroler fuzzy PD untuk menjaga suhu di dalam CSTR tetap berada pada suhu kerja. Kesalahan sensor yang terjadi pada sistem di identifikasi untuk menentukan kategori-kategori kesalahan sensor. Tiap kategori memiliki nilai-nilai kompensasi terhadap kesalahan yang terjadi. Dengan adanya kompensasi tersebut maka proses pada CSTR dapat beroperasi dengan baik meskipun terjadi kesalahan pengukuran pada sensor.


ABSTRACT

Continuous Stirred Tank Reactor CSTR is a non-linear plant that used in many industries such as chemical industries to mixes chemicals matters. The process in CSTR has its own working temperature which came from the hot steam that flow in the tanks wall by the tube to work properly so that it has to be controlled due to its high sensitive character to the changes of temperature. The temperature inside the tank is measured by sensors. The controller take the information from the sensor and result the control signal so that the process would work properly. Measurement error by the sensor could make the process work inappropriately moreover the process could be shutdown. Fault Tolerant Control FTC gives compensation to the measurement error by the sensor so that the process can work properly even theres an error. In this Final Project a fuzzy PD controller is designed to keep the CSTRs temperature stay in working temperature. The system could be identified due to the measurement error by the sensor. This result categories of the measurement errors. Each category has its own compensation value to the measurement errors. With these compensations CSTR could work properly even theres an measurement errors.
