renewable energy sources like wind, sun, and hydro are considered as a reliable alternative to the traditional energy sources such as oil, natural gas, or coal. this paper describes modeling and simulations to determine a method for the power performance evaluation of autonomous wind turbine system. a speed control regulator is utilized to control the dc bus voltage. the inverter gate’s signals...

Traditional weight adjustments for survey sampling error are often constructed through multiple stages, where design weights are based on the inverse of the probability of selection, and in a separate stage nonresponse adjustments are derived from weighting cells or classes, or based on model-deduced response propensities. More recent efforts by Little and Vartivarian (2003) have advocated the ...

This paper contains the design of a three stage solar battery charge controller and a comparative study of this charge control technique with three conventional solar battery charge control techniques such as 1. Constant Current (CC) charging, 2. Two stage constant current constant voltage (CC-CV) charging technique. The analysis and the comparative study of the aforesaid charging techniques ar...

In a modern, and complex power system (PS), robust controller is obligatory to regulate the frequency under uncertain load/parameter change of system. addition this, presence nonlinearities, load control (LFC) Power System becomes more challenging which necessitates suitable, controller. Single stage does not perform immensely against aforesaid changed conditions. So, novel non-integer/fraction...

in this paper the design, implementation, and evaluation of an experimental-scale potato yield monitoring system is presented. the main objective of this research was to develop a method for accurate mapping of potato yield. at the first stage an instantaneous yield monitoring system was mounted on a potato harvesting machine. this system consisted of a weighing tray, two load cells, a shaft rp...

This paper presents an alternative technique for the adaptive control of power electronic converter circuits. Specific attention is given to the adaptive control of a dc–dc converter. The proposed technique is based on a simple adaptive filter method and uses a one-tap finite impulse response (FIR) prediction error filter (PEF). The method is computationally efficient and based around a dichoto...

the aim of this paper is to investigate a novel approach for output feedback damping controller design ofstatcom in order to enhance the damping of power system low frequency oscillations (lfo). the design ofoutput feedback controller is considered as an optimization problem according with the time domain-basedobjective function which is solved by a honey bee mating optimization algorithm (hbmo...

this paper proposes an approach for the minimum time swing upof a rotary inverted pendulum. our rotary inverted pendulum is supported bya pivot arm. the pivot arm rotates in a horizontal plane by means of a servomotor. the opposite end of the arm is instrumented with a joint whose axisis along the radial direction of the motor. a pendulum is suspended at thejoint. the task is to design a contro...

Step adjustment for humanoid robots has been shown to improve gait robustness, while timing adjustment is often neglected in control strategies. In this paper, a new walking controller is proposed that combines both step location and timing adjustment for generating robust gaits. In this approach, step location and timing are decided, based on the Divergent Component of Motion (DCM) measurement...
