This paper presents compare results performance between two conventional controllers for bicycle robot. The bicycle speed control system was a highly nonlinear model multivariable and absolutely unstable. It has used for testing various design control techniques for low power. The objectives of this paper had to developed speed control which derived the mechanic model and experiment. Controllers are Proportional-Integral-Derivatives (PID) and on-off dynamic control. The dynamic system which also includes not stable friction effects the linear zed system model is used as a basis for the design to apply to speed. Computer simulation and experiment have been done controller are capable to control output speed wheel control system successfully. The results show PID controller better then on-off dynamic controller.

This paper presents how to design and build electrical protection equipment to apply for a wind turbine generator system which is modeled on low voltage 3 phase 380 volts system. This electrical equipment acts as a switch to open-close an electrical circuit to prevent an electrical system as well as equipments or devices in the system. It will open the circuit quickly and decrease the contact arcing of a circuit breaker. The implementation of power electronic properties is used instead of mechanical parts which is called “Solid-State Beaker”. This article presents a method of solid-state breaker simulation on the mathematical analysis via MATLAB/ Simulink program in the cases of fault occurring in an electrical system. The simulation is used as a comparison when it is brought into the system. The fault voltage is detected by RMS Method which is implemented in LAB View program. The detection signal will be sent to the solid-state breaker and order it to cut off all three lines simultaneously to confirm the efficient running of solid- state breaker. But this paper has not yet considered the effect of Harmonic.

This paper presents the development of a low rate and low power consumption low rate wireless network. Low rate wireless networks are cheap and comprised of a small fully autonomous processing communication and remote control devices. The purpose of this study is to develop the system for remote wireless lighting system. They will work with wireless network system (WNS). WNS has been restricted power supply communication distance and low computing power. But they will work with network in vast area send and receive raw data from each network node. It has the ability to cooperatively collect data and retransmit in order to process or alert. The step of the experiment is creating main node and sub node in lighting area and transmission of control data between them with less electrical wiring. When wireless node not receiving or transmitting data the module can be switched into the sleep mode low power consumption mode. We can reduce the use of electrical wiring insulated insulation material or other that related to and include energy too.

This paper presents the development of a low rate and low power consumption wireless sensor network. Wireless sensor networks are cheap and comprised of a small fully autonomous processing communication and sensing devices. The purpose of this study is to develop the system for monitoring and flood warning. They will work with wireless sensor network (WSN) system. WSN has been restricted power supply communication distance and low computing power. But they will work with network in vast area send and receive raw data from each sensor node. It has the ability to cooperatively collect data and retransmit in order to process or alert. The first step of the experiment is creating main node and sub node in flooding area and finds transmission of data between them. When sensor node is not receiving or transmitting data the module can be switched into the sleep mode low power consumption mode

The paper presents a development of monitoring system for a prototype wind turbine system. The proposed monitoring system is developed under Labview environment. The system can connect to the wind turbine online via internet. The system will collect the monitored values and install values into memory. Simultaneously the system can show the values in Real-Time. The operator can observe the wind turbine by the monitoring system and can take an action on time if the wind turbine is not working properly. The results of the monitoring system indicate that the monitoring system is be able to working properly the data can be used to investigate the wind turbine for system analysis. This is very important for wind turbine in order to supply energy to consumer stably.
