Abstract

Perkembangan pesat pada bidang militer mengakibatkan majunya teknologi persenjataan. Dengan begitu teknologi robot dapat diaplikasikan pada alat utama sistem pertahanan (alutsista) salah satunya yaitu meriam pada kapal tempur. Meriam merupakan salah senjata penting pada kapal tempur yang berfungsi menghancurkan sasaran yang berada di atas permukaan air, udara, atau darat sebagai bantuan tembakan kapal. Sasaran meriam berupa kapal yang bergerak. Meriam pada kapal dapat dikendalikan secara otomatis sehingga performa meriam semakin baik. Performa dari meriam yaitu kecepatan membidik dan mengunci, keakuratan, dan stabilitas meriam. Kontrol meriam berupa pengaturan sudut elevasi dan azimuth posisi laras meriam dimana juga memperhatikan lintasan gerak peluru dan keakuratan peluru. Untuk menaikkan keakuratan peluru ketika sasaran bergerak adalah dengan memprediksi lintasan sasaran selanjutnya. Pada penelitian ini meriam mengarah ke titik impact yaitu titik dimana bila proyektil ditembakkan proyektil akan sampai pada sasaran yang bergerak. Titik impact didapatkan dengan prediksi lintasan dengan metode polynomial regression. Metode dalam membuat kontroler yaitu linear Quadratic Tracking (LQT). Linear Quadratic Tracking (LQT) merupakan sistem pengaturan linier yang keluarannya mengikuti (tracking) jalur yang telah ditetapkan melalui masukan. Pada penelitian dilakukan variasi kecepatan sasaran yang bergerak yaitu 5 m/s, 10 m/s, dan 15 m/s dan variasi lintasan sasaran sebagai masukkan untuk diprediksi yaitu lintasan berbentuk garis lurus, kurva kuadrat, dan kurva kubik. Polynomial regression dapat memprediksi lintasan sasaran selanjutnya yang kemudian digunakan untuk mencari titik impact. Meriam dapat mengikuti masukkan yang berupa lintasan titik impact ketika terdapat gangguan maupun tidak.

The rapid development in the military field has resulted in the advancement of weapon technology. As a result, robotic technology can be applied to the main weapon systems of defense equipment (alutsista), one of which is the cannons on naval ships. Cannons are important weapons on naval ships that are used to destroy targets on the surface of water, in the air, or on land by providing fire support to the ship. The targets of the cannons are usually moving ships. The cannons on ships can be controlled automatically, thereby improving their performance. The performance of a cannon includes its aiming and locking speed, accuracy, and stability. The control of the cannon involves adjusting the elevation and azimuth angles of the cannon barrel position while also considering the trajectory and accuracy of the projectile. To increase the accuracy of the projectile when the target is moving, it is necessary to predict the target's trajectory. In this research, the cannon is aimed at the impact point, which is the point where the projectile will hit the moving target. The impact point is determined by predicting the trajectory using the polynomial regression method. The control system used is the Linear Quadratic Tracking (LQT). Linear Quadratic Tracking (LQT) is a linear control system where the output follows (tracks) a predefined path based on input. The research includes variations in the speed of the moving target, namely 5 m/s, 10 m/s, and 15 m/s, and variations in the target trajectory as inputs to be predicted, including a straight-line trajectory, quadratic curve trajectory, and cubic curve trajectory. Polynomial regression can predict the next target trajectory, which is then used to find the impact point. The cannon can follow the input, which is the trajectory of the impact point, whether there is disturbance or not.
