Abstract

Hardware in the Loop Simulation (HILS) is intended to reduce time and development cost of control system design. HILS systems are mostly built by integrating both controller hardware and simulator software where the software is not an open source. Moreover, implementing HILS by using manufactured system is costly. This paper describes the design and implementation of HILS for Electric Ducted Fan (EDF) rocket by using open-source platform for development with middleware. This middleware system is used to bridge the data flow between controller hardware and simulator software. A low-cost ATMEGA 2560 8-bit microcontroller is used to calculate rocket’s attitude with Direction Cosine Matrix (DCM) algorithm and PID controller is employed to regulate rocket’s dynamics based on desired specifications. X-Plane 10 simulator software is used for generating simulated sensory data. The test results validate that HILS design meets the defined specifications, i.e. angle difference of 0.3 degrees and rise time of 0.149 seconds on pitch angle.

Abstract

Pada penelitian ini dibahas perancangan sistem lokalisasi sumber suara dengan menggunakan metode Time Difference of Arrival (TDOA) dan metode Difference of Time of Flight (DTOF). TDOA merupakan metode penentuan posisi sumber suara berdasarkan pada persamaan hiperbola pada bidang koordinat dan hubungan selisih titik fokus hiperbola dari sinyal-sinyal yang diperoleh pada beberapa sensor berupa mikrofon dengan waktu kedatangan yang menggunakan waktu mutlak tiba di mikrofon tertentu. DTOF merupakan metode penentuan posisi sumber suara yang diturunkan berdasarkan perbedaan waktu propagasi sinyal dari sumber suara ke setiap mikrofon saat mikrofon dipicu. Sebagai pembuktiannya dilakukan dengan dua cara. Pertama, simulasi dengan waktu setiap mikrofon ialah jarak mikrofon terhadap sumber suara dibagi dengan kecepatan suara. Kedua, eksperimen dengan waktu setiap mikrofon ialah hasil rekaman suara yang waktu tundanya diperoleh dengan membandingkan Korelasi Silang dan Korelasi Silang Umum. Berdasarkan simulasi dan eksperimen dapat disimpulkan bahwa metode TDOA menghasilkan akurasi yang lebih baik.
