The scope of inverted pendulum has been widely studied as one of the notable research with respect to standing in balance. The concept of this pendulum is similar to missile guidance, meaning that the center of drag is ahead that of gravity. Mathematical model of inverted pendulum on a cart is moreover presented in this paper. Various rewarding par...

The monitoring condition of the centrifugal pump is closely related to fault detection and diagnosis. It usually uses vibration signals. However, under certain conditions, it is not possible to install the accelerometer on the machine due to certain conditions and environments. Current signals can be used to replace vibration signals. This method i...

The most human The most human form of energy today is electricity. While one of the fuels capable of producing electricity is biogas. Biogas produced by cattle farmers has great potential in Indonesia. However, from the electricity sector the generator set output still cannot produce good stability if there is a change in load. The speed of rotatio...

This paper proposes a scheme to improve regenerative ABS technology that already exists today by adding accommodation faults to the control system. The nominal control algorithm used is a sliding mode control so that system nonlinearities can be handled properly. The proposed method then is called sensor/actuator fault tolerant sliding mode control...

Currently, biogas as an alternative fuel has been widely used in the community, including in lamps and biogas stoves. There has been a surplus of biogas in some production regions due to a relatively small need for biogas fuel. So that most biogas users utilize the surplus to become generator fuel. Yet, in the application there is a drawback, namel...

Energy Is one of impoertant thing beside raw of material to produce nickel In order to meet energy requirement to produce Nickel through the process of smelting pyro metallurgy, PT. Vale Indonesia operates three hydroelectric power plants: Larona, Balambano and Karebbe. These plants generate 365 megawatts of power that supplies the electricity to o...
Article
The control system performance of the wind turbine can be unexpected due to the minor fault of its components, such as bias fault in its speed sensor and its converter system. Indeed, the lack of treatment to these faults lead to major problem. This paper discusses the control system design of generator rotor speed that is tolerant of faulty sensor...

The Larona River Basin which cover an area of 2477 km2, including the three cascading lakes: Matano, Mahalona, and Towuti Lakes, is a strategic watershed which acts as the water resource for three hydropower plants that supply 420 Megawatt of electricity to power a nickel processing plant and its supporting facilities and electricity need of the su...
Conference Paper
Absorption of H2S is one of the important part in biogas purification.. This process requires a purification system to reduce the content of harmful gas. The maximum tolerance of H2S content for biogas generator set input is 5 ppm, while measured input of H2S in cow manure has a concentration range from 43 to 45.5 ppm. Therefore, it needs proper op...

In relation to improve wind energy production, efforts to increase the extraction of wind energy should be done when there is a decrease in wind power. The decline occurs when there is a change in wind speed. At low wind speed operating range, such as in Indonesia, the controller optimizes power extraction through wind turbine rotor regulation foll...

The extraction of wind energy should be conducted especially for decline condition in wind power in order to intensify electrical power production. This paper introduced the use of supervisory control scheme which consists of a regulatory control level and a supervisory level. The first level has a function to keep the wind turbine system produces...
