Brushless Direct Current Electric Motor Design with Minimum Cogging Torque Muhammad Nizam; Hery Tri Waloyo; Inayati .
Proceeding of the Electrical Engineering Computer Science and Informatics Vol 1: EECSI 2014
Publisher : IAES Indonesia Section

Cogging torque is one of the factors that influence electric motor efficiency. Many methods have been used to reduce the cogging torque. One of the methods is the determination of the number of slots and poles fraction. This study was intended to determine the number of slots and poles fraction to get a minimum of cogging torque. Research was done by ANSYS software. By varying the number of slots and poles, the data cogging torque and torque ripple were observed. It was found that the lesser difference between the number of slots and poles produced lower cogging torque. More numbers of slots would reduce the cogging torque. The smallest cogging torque was produced at difference in the number of slots and poles of 1 and 2. For slots more than four, the cogging torque produced were irregular.

Publisher : IAES Indonesia Section

This study deals with the effect of humidity and contamination of salt on insulation resistance and polarization index. It investigated experimentally and is also analyzed by using its equivalent circuit. Surface leakage and absorption currents were measured to interpret the quality of insulation winding of a motor. The result shows that in all conditions, the value of absorption current is constant during the testing, meanwhile due to effect of humidity and contamination the leakage current is much larger than normal conditioned motor. Data obtained from insulation resistance test are used to calculate the resistance to ground (RTG) and capacitance to ground (CTG). RTG and CTG are then used as value of components on equivalent circuit for simulation matter. The simulation result using equivalent circuit is reasonable agree with the experiment done.

Optimization of Straight Movement 6 Dof Robot Arm With Genetic Algorithm R Suryoto Edy Raharjo; Oyas Wahyunggoro; Priyatmadi .
Proceeding of the Electrical Engineering Computer Science and Informatics Vol 1: EECSI 2014
Publisher : IAES Indonesia Section

This paper proposes a genetic algorithm (GA) to optimize the straight movement of the robot arm for 6 DOF. The objective function of the GA is proposed to find the optimal values of the movement of the robot arm in a straight line trajectory. As more and more levels of Degree of Freedom (DoF), the more difficult to achieve precision, especially during straight motion from the starting point (initial point) to the point of destination (final point), which is affected by the determination of the swivel angle of each actuator, the linearity of the trajectory length straight-effector motion, and the number of Intermediate Point required. Forward kinematics is used to find the coordinates of the end effector, and a linear function of a straight line from the starting point (initial point) to the point of destination (final point) is used as the objective function of GA.

This paper investigates the robustness of the pneumatic positioning system controlled by Self-regulation Nonlinear PID (SNPID) controller. This controller is executed by utilizing the characteristic of rate variation of the nonlinear gain that are readily available in Nonlinear PID (NPID) controller. A Self-regulation Nonlinear Function (SNF) is used to reprocess the error signal with the purpose to generate the value of the rate variation, continuously. Simulation and experimental tests are conducted. The controller is implemented to a variably loads and pressures. The comparison with the other existing method i.e. NPID and conventional PID are performed and evaluated. The effectiveness of SNPID + Dead Zone Compensator (DZC) has been successfully demonstrated and proved through simulation and experimental studies

Capacitor Motor as Low-Power, Low-Speed Single-Phase Generator Hari Santoso; Rini Nur Hasanah; Budiono Mismail; I Nyoman Gde Wardana
Proceeding of the Electrical Engineering Computer Science and Informatics Vol 1: EECSI 2014
Publisher : IAES Indonesia Section

In this paper, some results of experiment on modification of induction motor into generator are described. Not as usually done on three-phase motor, the modification has been done on capacitor motors normally supplied with single-phase source. The resulted induction generator should be able to self-excite and has been intended for low-power, low-speed applications. These applications are prospective for example in rural renewable energy generations and as motors for some special electric vehicles. Machine modification instead of total design-production or new machine acquisition is considered more appropriate for remote rural electrification. Distance and transportation difficulties, unavailability of nearby machine industry, lack of human resources with ‘high-tech savvy’, besides the low purchasing power of population in remote rural areas are some reasons behind the consideration. Experiment results indicated that voltage generation up to nominal value is not always easy to attain in a capacitor motor, even when functioning beyond its synchronous speed. An additional pre-charged capacitor should be used to initiate voltage generation. During start-up, load and the pre-charged capacitor had to be removed from generator to avoid capacitor discharge. Load could then be added gradually once generator approached its nominal output value. It was also shown that in order to generate power the generator must be rotating over its synchronous speed. The resulted frequency values did not vary linearly to the rotation speed and the obtained efficiency was still low.

Contouring Performance Study of a Fuzzy-based Practical Controller on an X-Y Table Purtojo .; Heru S. B. Rochardjo; Gesang Nugroho; Herianto .
Proceeding of the Electrical Engineering Computer Science and Informatics Vol 1: EECSI 2014
Publisher : IAES Indonesia Section

This article presents a contouring performance of an improved practical fuzzy-based nominal characteristic trajectory following (NCTF) controller. The proposed fuzzy-based NCTF controller structure for continuous motion control is slightly different from the normal NCTF controller. It is composed of a nominal characteristic trajectory (NCT) and a fuzzy compensator designed using the practical design approach. Therefore, simple and easy of controller design are maintained. The NCT constructed through establishing procedure and the Mamdani type fuzzy compensator is designed according to the available information provided by NCT and the hardware specification. The contouring performance was evaluated by measuring the response of the system providing circle shape through simulation. The simulation result shows that the controller is promising as a practical controller for continuous motion.

Comparison of Control Methods PD, PI, and PID on Two Wheeled Self Balancing Robot Bhakti Yudho Suprapto; Djulil Amri; Suci Dwijayanti
Proceeding of the Electrical Engineering Computer Science and Informatics Vol 1: EECSI 2014
Publisher : IAES Indonesia Section

A robot must employ a suitable control method to obtain a good stability. The Two-Wheeled Self Balancing Robot in this paper is designed using a MPU-6050 IMU sensor module and ATmega128 microcontroller as its controller board. This IMU sensor module is employed to measure any change in the robot’s tilt angle based on gyroscope and accelerometer readings contained in the module. The tilt angle readings are then utilized as the setpoint on the control methods, namely PD (Proportional Derivative), PI (Proportional Integral), or PID (Proportional Integral Derivative). Based on the conducted testing results, the PID controller is the best control strategy when compared to the PD and PI control. With parameters of Kp = 14, Ki = 0005 and Kd = 0.1, the robot is able to adjust the speed and direction of DC motor rotation to maintain upright positions on flat surfaces.
