Abstract

Perkembangan teknologi pada suspensi kendaraan bertujuan untuk memberikan efek kenyamanan dan keamanan dalam berkendara. Low Bandwidth Active Suspension (LBAS) adalah sistem suspensi aktif dengan konsumsi energi yang lebih sedikit dibandingkan dengan High Bandwidth Active Suspension (HBAS). Kendali PID (Proportional Integral Derivative) adalah sebuah pengendali konvensional, sederhana, praktis, dan tidak memerlukan semua state untuk dilakukan pengukuran serta tidak memiliki observer, sehingga implementasinya akan lebih mudah. Pada Tugas Akhir ini dilakukan desain kendali PID pada LBAS. Desain kendali PID menggunakan metode auto tuning, dan Ziegler-Nichols pada tiga kondisi pengukuran. Pengukuran I pada percepatan sprung-mass, pengukuran II pada defleksi suspensi dan pengukuran III pada deformasi ban. Analisa performa LBAS menggunakan time response dan nilai RMS (root mean square) serta meninjau nilai comfort gain. Hasil penelitian yang diperoleh bahwa performa LBAS dengan kendali PID lebih baik dari sistem pasif pada pengukuran I. Nilai RMS pada percepatan sprung-mass sebesar 0,45 m/s2 , defleksi suspensi sebesar 0,0094 m dan deformasi ban sebesar 0,0013 m. Nilai comfort gain pada kendali PID sebesar 6,56% untuk percepatan sprung-mass, 15,37% untuk defleksi suspensi dan 2,62% untuk deformasi ban terhadap sistem suspensi pasif. ==================================================================================================== The development of vehicle suspension technology aims to provide comfort and security effects in driving. Low Bandwidth Active Suspension (LBAS) is active suspension system with less energy consumption compared with High Bandwidth Active Suspension (HBAS). PID controller (Proportional Integral Derivative) is a conventional controller, simply practical, does not require all state for measurement and does not have an observer, so that the implementation will be more easily. On this Final Project, PID control design is done on LBAS. PID control design uses auto tuning method and Ziegler-Nichols on three measurements conditions. The first measurement is on sprung-mass acceleration, the second is on suspension deflection measurements and the last is on tire deformation. Performance Analysis of the LBAS uses time response and RMS (root mean square) value also reviews the value of comfort gain. The result of research is obtained that LBAS performance with PID control is better than passive system in the first measurement. The RMS value on the sprung-mass acceleration is 0.42 m/s2 , suspension deflection is 0.0089 m and tire deformation is 0.0013 m. The comfort gain value on PID control is 6.56% for the sprung-mass acceleration, 15.37% for suspension deflection and 2.62% for tire deformation toward passive suspension system.
