Abstract

Sensor temperatur dari separate line calciner (SLC) preheater Pabrik Tuban II di PT. Semen Indonesia (Persero) Tbk sering mengalami perbaikan akibat kesalahan pembacaan. Pada Tugas Akhir ini dilakukan perancangan sistem kontrol yaitu active fault tolerant control (AFTC) yang mampu bekerja ketika terdapat suatu kesalahan yang terjadi pada sensor dan dapat mempertahankan performansinya. Langkah awal yang dilakukan adalah pemodelan dari proses yang terjadi pada SLC preheater. Langkah kedua adalah merancang observer dengan pendekatan modified PD descriptor observer. Langkah terakhir adalah merekonfigurasi sistem kontrol. Hasil simulasi menunjukkan bahwa dari uji kesalahan bias, sensitivitas, dan noise diperoleh kestabilan temperatur pada setpoint 890 oC dengan maximum overshoot sebesar 5,6%, error steady state sebesar 0%, dan settling time 50 detik. ============================================================================================ Temperature sensor of the separate line calciner (SLC) preheater Tuban II Cement Plant in PT. Semen Indonesia (Persero) Tbk often have repaired because of an error reading. On this final project, designing control systems namely active fault tolerant control (AFTC) who are able to work when there is a fault that occurs in the sensor and can maintain the performance. The first step undertaken was the modeling of processes that occur at the SLC preheater. The second step is to design observer with a modified PD descriptor observer approach. The final step is the reconfiguration control system. Simulation results show that the test of bias, noise, and sensitivity, temperature stability obtained at set point 890 °C with maximum overshoot of 5,6%, steady state error of 0%, and settling time of 50 seconds.
