Abstract
Traction control pada kendaraan listrik berguna untuk mengurangi gejala tergelincirnya roda pada permukaan jalan. Namun, disturbance berupa drag force udara dan kesalahan plant pada ketidakpastian model matematis dapat mengakibatkan kegagalan pada sistem sehingga mengganggu stabilitas kemudi. Tugas akhir ini mengajukan pendekatan fault tolerant berdasarkan pada skema maximum transmissible torque estimation (MTTE) yang digunakan untuk mengurangi kedua faktor tersebut dan juga untuk mencegah kendaraan listrik dari tergelincir. PI observer digunakan untuk meningkatkan stabilitas kemudi dari pendekatan MTTE. Adapun respon yang diuji berupa sistem open loop, sistem fault tolerant traction control (FTTC), serta FTTC dengan kesalahan pada inersia roda sebesar 0,3 Kg.m2, 0,4 Kg.m2, dan 0,5 Kg.m2. Pada uji coba algoritma FTTC, ditemukan bahwa sistem FTTC dapat mengurangi slip ratio sebesar 0,72 dari sistem open loop dan dapat mengatasi kesalahan pada inersia roda.

Traction control on electric vehicles is useful to reduce the symptoms of wheel slip on the road surface. However, the disturbance in the form of drag force and plant errors in the uncertainty of mathematical models can result in failure of the system which disrupts steering stability. This final project proposes a fault tolerant approach based on the scheme of maximum transmissible torque estimation (MTTE) which is used to reduce both of these factors and also to prevent electric vehicles from slipping. PI observers are used to improve steering stability from the MTTE approach. The responses tested were in the form of an open loop system, fault tolerant traction control (FTTC) system, and FTTC with a fault in wheel inertia of 0,3 Kg.m2, 0,4 Kg.m2 and 0,5 Kg.m2. In the FTTC algorithm test, it was found that the FTTC system can reduce the slip ratio by 0,72 from the open loop system and can overcome errors in wheel inertia.
