1. Introduction This paper proposes a control technique for navigation of intelligent mobile robots. Cooperative behaviours using a colony of robots are becoming more and more significant in industrial, commercial and scientific application. Applications in the area of service robotics demand a high degree of system autonomy, which robots without learning(More)
Control strategies for extracting the three-phase reference currents for shunt active power filters are compared, evaluating their performance under different source conditions with PI and Fuzzy Controllers in MATLAB/Simulink environment When the supply voltages are balanced and sinusoidal, the two control strategies are converge to the same compensation(More)

OBJECTIVE The study was done to determine the prevalence of malocclusion and orthodontic treatment among orphan children. MATERIALS AND METHODS The sample consisted of 165 orphan children aged between 12 and 15 years. A clinical examination was used to determine the orthodontic treatment need according to the Dental Aesthetic Index (DAI). The statistical(More)
Distributed Static Compensator (DSTATCOM) is a widely used custom power device in distributed network to perform the power quality improvement tasks like harmonics reduction, power factor correction and maintain reduces constant dc bus voltage. This paper investigates a new topology based on a Distributed Static Compensator (DSTATCOM) coupled with a(More)
This paper proposes a zero-voltage-transition (ZVT) pulsewidth-modulated (PWM) synchronous buck converter, which is designed to operate at low voltage and high efficiency typically required for portable systems. A new passive auxiliary circuit that allows the main switch to operate with zero-voltage switching has been incorporated in the conventional PWM(More)
