Abstract

Motor DC merupakan sistem penggerak yang paling banyak digunakan di bidang industri, otomasi, robotika, ataupun lainnya. Penggunaan sistem kendali banyak diterapkan untuk pengaturan pergerakan kecepatan ataupun posisi dari motor DC. Pada penelitian ini, state feedback controller dan penambahan kendali integral dengan estimator digunakan untuk mengendalikan posisi motor DC. Sistem dibuat berbasis real-time operarting system (RTOS) untuk pembacaan sensor, perhitungan matematis kendali, dan pengiriman sinyal pulse width modulation (PWM). Pengendalian dilakukan pada motor DC Quanser yang terhubung dengan Arduino Mega 2560 untuk membaca sensor encoder dan menampilkan data pengujian. Hasil pengujian menunjukkan bahwa state feedback controller dapat mengendalikan posisi motor DC dengan nilai penguat K sebesar 2,66 dan 115,37, nilai penguat N_bar sebesar 0,49 dan nilai estimator sebesar 7,75 dan 0,26. Penggunaan RTOS sebagai inti pemrograman dapat menyelesaikan permasalahan dalam pengerjaan task-task­ seperti pembacaan sensor, perhitungan parameter kendali, dan pengiriman sinyal kendali tanpa terjadi error selama pengujian sistem. Hasil analisa menunjukan keluaran sistem kendali posisi memiliki nilai overshoot sebesar 2,63% pada pengujian pertama dan 2,66% pada pengujian kedua.

Abstract

The presence of robots that can assist humans with heavy or dangerous work makes the need for robots more pressing at the moment. One type of robot needed is a robot arm, which is widely used in the manufacturing industry, such as in the assembly process and pick and place. The types of robotic arms used vary both in terms of configuration and the number of degrees of freedom. However, with different types of robotic arms, different models of movement are used. Therefore, research related to the modeling of the robotic arm continues to be carried out to obtain the appropriate movement of the robotic arm. One of the methods used as a first step in designing a robotic arm movement model is kinematics analysis. Kinematics analysis aims to analyze the movement of the robot arm without knowing what force causes the movement. This paper aims to produce an ideal movement model for the AX-12A 3-DoF robotic arm using forward kinematic and inverse kinematic analysis using two methods, the Denavit-Haterberg method and the geometric approach method. The difference from other papers is that this paper makes the kinematics model using Robotic, Vision, and Control (RVC) tools based on the Peter I. Corke model on MATLAB software first before implementing it on hardware. The results show that the error percentage for the forward kinematic model is 1.04% and the inverse kinematic is 0.76%, which means the two models achieved the target that the model’s error maximum must be less than 2%.
