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.
