Abstract

This paper aims to design and simulate an Electrical Permanent Magnet Generator (EPMG) for rural area wind power plant. The generators available in the market mostly are a kind of high speed induction generator which requires high rotational speed and an electricity to generate a magnetic field. In this project, a radial flux generator is designed to have a low speed rotation using permanent magnet type Neodymium Iron Boron (NdFeB). Software used for designing is Finite Element Method (FEM) Magnet software basis. The model also examined with Simulink/Matlab environment. Extensive modifications are applied to get optimum result by changing generator diameter, number of coils, the copper wire diameter, number of poles, and used slots. The simulation results obtained generator speed 500rpm, the average series voltage is 145 Vrms, the generator requires 18cm diameter, number of turn for each coil is 55, diameter of the copper wire used is 0.6mm, and number of poles is 8 pairs and 12 unit slots.

Abstract

Fish food is one of the factors that play an important role in the growth process of fish. Fish growth can run optimally if the amount of food, food quality and nutritional content are met properly. For this reason, it is necessary to improve fish farming skills through the manufacture of independent fish food for fish cultivators. This activity is carried out based on partner problems, namely the fish cultivator group in Parangargo Village, Wagir District, Malang Regency. This activity uses multiple methods, namely observation, interviews, lectures and discussions. This activity is equipped with indicators of achievement to facilitate evaluation. This activity was carried out in stages in two locations. The first location was carried out in the Edu Park Hall, Faculty of Agriculture and Animal Husbandry, University of Muhammadiyah Malang and the second was carried out in food processing and fish farming, Probolinggo Regency. The result of this activity is an increase in the knowledge (cognitive) aspect of partner communities about self-fooding, which has increased. In addition, participants also experienced an increase in fish fooding management. In terms of skills in processing alternative foods, an increase of 50%, as measured by the active participation of participants in fish food processing practices.

Abstract

This study aims to design a control scheme that is capable to improve performance and efficiency of brushless DC motor (BLDC) in operating condition. The control scheme is composed of sliding mode controller (SMC) with proportional-integral-derivative (PID) sliding surface. The PID sliding surface is used to improve the system transient response. Then, the SMC-PID is optimized by genetic algorithm optimization for further improvement on the stability and robustness against nonlinearities and disturbances. Chattering problem that appear in the SMC is minimized by employing an adaptive switching gain for the SMC that is integrated with Luenberger Observer. Lyapunov function candidate is applied to guarantee the stability of the system. Simulation on the proposed work is done in Matlab Simulink. Results of the simulation works indicate that the proposed control scheme can improve the transient response, the stability and robustness of the BLDC motor compared to the conventional SMC in the existence of nonlinearities and disturbances.
