Abstract

Robotics vision is applying technology on the camera to view the environmental conditions as well as the function of the human eye. Colour object tracking system is one application of robotics vision technology with the ability to follow the object being detected. Several methods have been used to generate a good response position control, but most are still using conventional control approach. Fuzzy logic which includes several step of which is to determine  the  value  of  crisp  input  must  be  fuzzification.  The  output  of  fuzzification  is forwarded to the process of inference in which there are some fuzzy logic rules. The inference output forwarded to the process of defuzzification to be transformed into outputs (crisp output) to drive the servo motors on the X-axis and Y-axis. Fuzzy logic control is applied to the color- based object tracking system, the system is successful to follow a moving object with average speed of 7.35 cm/s in environments with 117 lux light intensity.

Abstract

Induction motors are electrical machines that operate based on electromagnetic principles to convert electrical energy into mechanical energy. In the oil and gas industry, electric motors are widely used for operational processes. This accounts for a large portion of operational costs. At the Fuel Oil Complex II operating unit, the 011P-109B drive motor for the LDO product pump was damaged, so the motor was replaced with one that exceeded the existing specifications, namely from 125HP to 150HP, 111.855 kW, 2 poles, and a frequency of 50 Hz. Research was conducted to test the efficiency of the motor. The method used in this test was a literature review of several publications that comply with national and international standards. Based on efficiency calculations, the 150HP induction motor has superior operational efficiency compared to the 125HP motor, with an average efficiency of 93.63% compared to 93.15%, as well as lower power loss of 4.8kW compared to the 125HP motor, which has a power loss of 5.01kW. The comparison results with the IEC 60034-30-1:2014 standard show that both motors are technically classified in the IE2 (High Efficiency) to IE2+ (Borderline IE3) category.
