Abstract
Teknologi Hybrid Electric Vehicle (HEV) menggabungkan kinerja Internal Combution Engine (ICE) dan motor listrik. ICE berlaku sebagai penggerak utama, dan motor listrik berlaku sebagai penggerak pembantu. Tetapi, pengembangan pada teknologi HEV masih sulit untuk dikembangkan karena konfigurasinya sangat kompleks. Selain itu terjadi permasalahan pada pembagian kerja antara ICE dengan motor DC pada saat akselerasi ataupun pada permasalahan regulasi. Permasalahan regulasi dapat terjadi pada saat terjadi pembebenan lebih pada kendaran berupa rem mekanik yang akan mempengaruhi penurunan kecepatan mesin bakar sehingga terjadi penurunan kecepatan pada HEV. Oleh karena itu perlu adanya suatu kontroler yang dapat dengan segera mengembalikan kecepatan HEV dengan mengatur kecepatan putar dari motor DC sebagai penggerak pembantu. Pada tugas akhir ini, digunakan kontroler State Dependent – Linear Quadratic Regulator (SD-LQR) untuk pengaturan kecepatan yang akan diimplementasikan pada simulator Parallel Hybrid Electric Vehicle (PHEV). Berdasarkan hasil pengujian, motor DC dapat membantu kinerja mesin bakar mempertahankan set point hingga ess dapat mencapai 0,05%. Berdasar hasil implementasi masih terdapat ess hingga 11,1%
