Abstract

The electric motor is one of the appliances that consume considerable energy. Therefore, the control method which can reduce energy consumption with better performance is needed. The purpose of this research is to minimize the energy consumption of the DC motor with maintaining the performance using Hybrid Fuzzy-PID. The input of the Fuzzy system is the error and power of the system. Where error is correlated with matric Q and power is correlated with matric R. Therefore, adjusting the fuzzy rule on error and power is like adjust matrices Q and R in LQR method. The proposed algorithm can reduce energy consumption. However, system response is slightly decrease shown from ISE (Integral Square Error). The energy reduction average is up to 5.58% while the average of ISE increment is up to 1.89%. The more speed variation in the system, the more energy can be saved by the proposed algorithm. While in terms of settling time, the proposed algorithm has the longest time due to higher computation time in the fuzzy system. This performance can be increased by tuning fuzzy rules. This algorithm offers a solution for a complex system which difficult to be modeled.

Abstract

The Development of Portal Elektro Information System is carried out to create solutions for administrative problems related to Internship and Final Project, especially students, lecturers, and Electrical Engineering staff. Moreover it is an effort to improve the quality of the system to be more innovative and support the needs of Electrical Engineering study program. The System of Portal Elektro covers student needs to carry out internship or final project, starting from implementation guidelines, proposal writing, until becomes final report. This information system is developed with Rapid Application Development method, and use Laravel framework with the concept of MVC (Model, View, Controller) which can separate application based on application components, such as: manipulation data, controller, and user interface. With the RAD method and Laravel framework, application development can be done quickly and structured making it easier for further development in the future. The developed system has been successfully tested and applied in the Electrical Engineering study program at UNS and is planned to be implemented in several other study programs.
