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)
Navigation of mobile robots remains one of the most challenging functions to carry out. Potential Field Method (PFM) is rapidly gaining popularity in navigation and obstacle avoidance applications for mobile robots because of its elegance. Here a modified potential field method for robots navigation has been described. The developed potential field function(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)
In this research study, direct torque and flux control of induction motor drive (IMD) using artificial intelligence based speed control loop (SCL) to minimize the ripple contents of the stator current, flux and electromagnetic torque, and also improving the speed response under transient and steady state conditions. It is quite difficult to optimize the(More)
