Abstract
Kegagalan sistem turbin angin akibat kesalahan minor pada komponen seperti aktuator dapat berakibat fatal karena seiring waktu berjalan akan menimbulkan kesalahan major yang membuat performansi terus menurun bahkan dapat mengakibatkan turbin angin berhenti beroperasi. Pada tugas akhir ini dilakukan perancangan sistem Fault Tolerant Control (FTC) dengan menggunakan observer yang mampu bekerja ketika terjadi kesalahan pada aktuator di sistem pengendalian kecepatan generator sehingga performansi sistem dapat terjaga. Langkah pertama yang dilakukan adalah membuat simulator turbin angin. Langkah kedua adalah merancang observer untuk mengestimasi kesalahan bias. Dalam hal ini gain observer dicari dengan menggunakan metode pole-placement. Dari Hasil simulasi diperoleh bahwa kesalahan bias maksimum yang masih bisa diakomodasi oleh sistem tanpa FTC adalah 0,7 pu, sedangkan dengan sistem FTC mampu meng-akomodasi kesalahan bias hingga 1,2 pu meskipun terjadi maximum undershoot sebesar 10,8% dan dapat menghasilkan nilai settling time yang lebih cepat sebesar 715 detik.

Failure in wind turbine system due to minor faults that are not dealt with immediately on components such as actuator could be a big problem for the system. It is because the fault will lead to major fault that will decrease the performance of the system and may even cause the wind turbine to stop operating. In this final project, Fault Tolerant Control (FTC) system using by observer that can work when there is a fault on actuator in the generator speed system control, so that system performance can be maintaned. The first step is to make simulator of wind turbine. The second step is to design observer to estimate the bias fault. In this case, the gain observer is searched by using pole-placement method. From the result of simulation, showed that the maximum refractive fault that could still be accommodated by the system without FTC was 0,7 pu. Whereas, FTC system could accommodate bias fault up to 1,2 pu, althought there was maximum undershoot of 10,8%. for settling time, it could resulting a faster settling time value of 715 seconds.
