ABSTRAK Paper ini bertujuan untuk menganalisa rangkaian sistem kendali putaran motor menggunakan Silicon Controlled Rectifier (SCR) atau Thyristor. Eksperimen sistem kendali putaran motor ini menggunakan dua rangkaian yang berbeda. Rangkaian pertama menggunakan dua sumber, yaitu sumber tegangan DC 12 v terhubung dengan motor universal secara seri dengan resistor dan SCR, sedangkan sumber tegangan DC variabel 0 sampai 1.5 v dihubung paralel dengan kapasitor dan resistor. Rangkaian kedua menggunakan satu sumber tegangan AC 5 v yang dihubungkan dengan saklar dan motor. Pada rangkaian kedua ini motor dihubungkan dengan potensio, SCR, dioda serta kapasitor yang dipasang paralel dengan sumber tegangan AC. Hasil eksperimen menunjukkan dalam rangkaian menggunakan sumber tegangan DC, motor DC akan berputar saat saklar S1 tertutup. Kondisi motor akan berputar lebih cepat ketika sumber tegangan variabel diatur lebih besar dari 0 v sehingga arus gate Ig lebih bear dari 400 mA. Adapun Eksperimen dengan sumber tegangan AC, motor akan berputar dengan menambahkan dioda D3 dan pengaturan kecepatan melalui potensio meter Rv sampai posisi maksimum.

<p>In this paper a dual open loop speed control system based on two independent PWM signals of small permanent magnet DC (PMDC) motors using PIC16F877A microcontroller (MCU) has been designed and implemented. The Capture/Compare/PWM (CCP) modules of the MCU are configured as PWM mode and the MCU is programmed using flowcode software package to generate two PWM signals with various duty cycles at the same frequency. A dual H-bridge channel chip SN754410 is used to drive the motors. The variation of PWM duty cycles is related directly to controlling the DC motors terminal voltage which directly proportional with speed of each motor. The complete PWM control system model has been simulated using proteus design suite software package. The development of hardware and software of the dual DC motor speed control system has been explained and clarified.</p>

In this report, a new-type two-joint articulated hopping robot with two stopper mechanisms is developed. The two rotary joints are actuated by two DC motors with reduction gears. In this new-type two-joint articulated hopping robot with two stopper mechanisms, the hopping motion actions are achieved by the two joint rotational dynamics and the two stopper mechanisms. Using the two stopper mechanisms, the angular momentums and momentums of the two links are transformed into the hopping motion action according to the law of conservation of angular momentum and momentum. Then, the hopping motion control system is constructed to fit the DC motor characteristics, and the effects of the stopper settings and the delay time of the control voltage of the DC motor on the hopping motion performance are experimentally investigated. Furthermore, the examples of the hopping motion control experiments are demonstrated, and it is confirmed that the forwards and backwards hopping motion actions can be successfully performed.

Exoskeleton Robot

Manusia ingin dilahirkan dalam kehidupan yang sempurna, baik jasmani maupun rohani. Tetapi dalam kenyataannya, manusia jauh dari sempurna. Salah satu ketidaksempurnaan yaitu kelumpuhan pada lengan. Penelitian yang sekarang berkembang yaitu robot exoskeleton. Exoskeleton merupakan struktur pendukung dari bagian luar tubuh. Robot ini memiliki aplikasi prospektif untuk rehabilitasi atau alat bantu. Sistem kontrol exoskeleton yang sukses bergantung pada pemahaman yang lebih baik dalam biomekanik gerak tubuh manusia dan mekanisme sensorik yang juga merupakan masalah penting dalam interaksi fisik manusia-robot. Robot siku lengan yang dikembangkan oleh Thomas menggunakan servo motor sebagai aktuator. Semakin berat beban, semakin besar torsi servo tersebut. Di Indonesia tidak dijumpai servo dengan torsi tinggi. Hanya motor DC yang banyak di pasaran. Untuk menekan biaya pengembangan robot lengan exoskeleton, penelitian menggunakan motor DC. Sistem kontrol diperlukan untuk membuat sebuah motor DC bergerak seperti layaknya motor servo. Sistem kontrol logika Fuzzy paling tepat untuk mengontrol motor DC. Sebuah prototype robot lengan exoskeleton dibuat. Motor DC sebagai penggerak lengan robot. Sistem kontrol Fuzzy pada robot dibuat menggunakan software SIMULINK/MATLAB. Gerak robot dibatasi dari 0o sampai 90o. Sistem akan diuji menggunakan SIMULINK/MATLAB dan dilakukan dengan interface prototype exoskeleton.

Data Parameter respon transient dari hasil pengujian prototype selama 20 detik, waktu tunda (td) = 1.16, waktu naik (tr) = 1.98, waktu puncak (tp) = 2.16 . Data parameter sistem kontrol Logika Fuzzy lebih baik daripada sistem kontrol sederhana yang dibuat. Humans want to be born in a perfect life, both physically and spiritually. But in reality, humans are far from perfect. One of the imperfections is arm paralysis. The current study is an exoskeleton robot. The exoskeleton is the supporting structure of the outer part of the body. This robot has a prospective application for rehabilitation or aids. Successful exoskeleton control systems rely on better understanding of the biomechanics of human body motion and the sensory mechanisms that are also important problems in human-robot physical interactions. The elbow arm robot developed by Thomas uses servo motors as actuators. The heavier the load, the greater the servo torque. In Indonesia there is no servo with high torque. Only DC motors are in the market. To reduce the development cost of robotic arm of exoskeleton, research using DC motor. A control system is needed to make a DC motor move like a servo motor. Fuzzy logic control system is most appropriate for control of DC motors. A prototype of an exoskeleton robot arm is made. DC motor as a actuator robot. Fuzzy control system on the robot is made using SIMULINK / MATLAB software. Robot motion is limited from 0o to 90o. The system will be tested using SIMULINK / MATLAB and done with prototype exoskeleton interface. SIMULINK / Matlab facilitate the manufacture of Fuzzy Logic that can control the motion of DC motors like servo motors. Data Parameter transient response from prototype test result for 20 seconds, Delay time (td) = 1.16, Rise time (tr) = 1.98, Peak time (tp) = 2.16. Data parameters Fuzzy Logic control system is better than the simple control system created.

At metallurgical enterprises, slab transfer devices are widely used, the principle of operation of which is to lift slabs in the steel casting area and transport them to the storage area. The article considers the existing control system of the slab transfer device. At the moment, the mechanism has a DC motor controlled by a thyristor Converter. This system is difficult to maintain and has a large size. As an upgrade, the installation of an asynchronous motor with a frequency Converter is proposed. In the Matlab environment, mathematical models of single-circuit and double-circuit DC motor control systems and a model of asynchronous motor with a short-circuited rotor have been developed. A vector control system is used as an AC motor control system. As a result of simulation performed analysis of the characteristics. As an optimization of the system with vector control, in order to reduce dynamic loads on the turntable, it is proposed to introduce an intensity setter into the system, the use of which provides the necessary restriction of accelerations and jerks, reduces shock loads on the mechanical components of the electric drive, including a reduction in the load on the turntable when lowering the slab.
