Abstract

This paper presents a stabilization control method for “x” configuration quadcopter. The control method used the combination of PD (Proportional Derivative) controller and PIAFC (Proportional Integral Active Force Control). PD is used to stabilize quadcopter, and PIAFC is used to reject uncertainty disturbance (e.g. wind) by estimating disturbance torque value of quadcopter. The PD with PIAFC provided better result where PIAFC could minimize uncertain disturbance effect. The simulation has successfully give comparation about controller performance (PD, PD-AFC, PD-PIAFC) by calculate RMS (Root Mean Square) value. PD with AFC gives better result than PD. AFC optimization using PI (PD-PIAFC) give best result if compared with PD or PD-AFC. PD-PIAFC has lowest RMS value of result control signal, 0.0389 for constant disturbance and 0.1008 for fluctuated disturbance.Keywords:“x” configuration quadcopter, stability, PD, PIAFC.

Abstract

This paper presents algorithm ingenerating trajectory for sealant process using captured image. Cartesian robot as auto-sealant in manufacturing process has increased productivity, reduces human error and saves time. But, different sealant path in many engine models means not only different trajectory but also different program. Therefore robot with detection ability to generate its own trajectory is needed. This paper describes best lighting technique in capturing image and applies edge detection in trajectory generation as the solution. The algorithm comprises image capturing, Canny edge detection, integral projection in localizing outer most edge, scanning coordinates, and generating vector direction codes. The experiment results show that the best technique is diffuse lighting at 10 Cd. The developed method gives connected point to point trajectory which forms sealant path with a point to next point distance is equal to 90° motor rotation. Directional movement for point to point trajectory is controlled by generated codes which are ready to be sent by serial communication to robot controller as instruction for motors which actuate axes X and Y directions.

Abstract

This paper present a control method “x? configuration quadcopter. The control method used PDAFC (Proportional Derivative Active Force Control). PD is used to stabilize quadcopter, and AFC is used to reject uncertainty disturbance (e.g. wind) by estimate disturbance torque value of quadcopter. By adding PD with AFC, better result is obtained, AFC can minimize uncertainty disturbance effect. The sensitivity toward uncertainty disturbance can be set from sensitivity constant to get best performance of disturbance rejection. Stability analysis of PDAFC was evaluated by Lyapunov stability theory.

Abstract

Robot Automated Guided Vehicle (AGV) secara luas diterapkan di berbagai tempat seperti pabrikasi dan manufaktur yang telah menggunakan sistem otomatis, khususnya pada area pergudangan. Ferlib AGV merupakan robot pembawa barang yang didesain khusus untuk membawa dan memindah barang. Robot Ferlib AGV diciptakan untuk memenuhi kebutuhan para pekerja dalam sistem tata kelola pergudangan di industri terutama pekerjaan yang bergerak dalam bidang ekspedisi pengiriman barang. Pada saat beberapa robot berjalan di ruang atau daerah kerja yang sama, terdapat masalah yang mungkin terjadi dalam manajemen lalu lintas salah satunya adalah tabrakan. Penelitian ini bertujuan untuk membuat sebuah sistem yang dapat membuat robot menuju ke posisi yang diinginkan dan sebuah sistem yang dapat menghindari terjadinya tabrakan untuk diimplementasikan pada robot Ferlib AGV sebagai robot pembawa barang. Ada dua jenis konflik yang dapat menyebabkan terjadinya tabrakan yaitu Node Conflict dan Opposite Conflict. Robot mendeteksi konflik menggunakan sensor Position Sensitive Device (PSD) jenis inframerah. Untuk menyelesaikan konflik antar robot dimulai dari perencanaan jalur yang sesuai, dan dasar efektivitas tugas penjadwalan pergerakan robot. Hasil dari sistem ini telah mampu membuat robot Ferlib AGV sebagai robot pembawa barang yang dapat membawa barang menuju posisi koordinat berdasarkan posisi yang diberikan, serta dapat mendeteksi konflik dan melakukan penghindaran berdasarkan jenis konflik yang terjadi. ABSTRACT Automated Guided Vehicle System (AGVs) robots are widely applied in various places such as manufacturing and manufacturing that have used automated systems, especially in warehousing areas. Ferlib AGV is a freight robot specifically designed to carry and move goods. The Ferlib AGV robot was created to meet the needs of workers in the warehousing governance system in the industry, especially jobs engaged in the transportation and transfer of goods. When several robots run in the same work space or area, there are problems that may occur in traffic management, one of which is a collision. This study aims to create a system that can make the robot go to the desired position and a system that can avoid collisions to be implemented on the Ferlib AGV robot as a freight robot. There are two types of conflicts that can cause collisions, namely Node Conflict and Opposite Conflict. Robots detect conflicts using an infrared sensor type Position Sensitive Device (PSD). To resolve conflicts between robots starts from the appropriate path planning, and the basic effectiveness of the task of scheduling robot movements. The results of this system have been able to make Ferlib AGV robots as goods-carrying robots that can carry goods to coordinate positions based on the given position, and can detect conflicts and avoidance based on the type of conflict that occurs.

Crude palm oil has a high free fattThis paper presents a control method for 3D independent actuators using PDAFC (Proportional Derivative Active Force Control). PD is used to stabilize the actuators, where as AFC is used to reject disturbance uncertainty by estimating disturbance torque value of actuator. Simulation result shows that PDAFC can minimize disturbance uncertainly effect. To test the performances of a control system actuator given disorder constant and sine. To research it uses cube as an actuator. when give the actuators disturbance with the constant value of 45, to achieve setpoint actuators takes 1 second. This condition is in all actuators whether it was the yaw, pitch and roll. When give the actuators disturbance with the sine, to achieve setpoint actuators takes 1.25 second. This condition is in all actuators whether it was the yaw, pitch and roll.
