In this paper, a hybrid integrator backstepping controller is proposed for robotic manipulators actuated with brushless dc motors in the presence of arbitrary uncertain inertia parameters of the manipulator and the electrical parameters of the actuators. The main features are: 1) the design, requiring at most the joint velocities and stator currents feedback, 2) the semiglobal asymptotic stabil...

This paper presents the design and implementation of an adaptive fuzzy logic controller for the speed control of brushless dc motors. The proposed system uses an adaptation of the slope of the membership functions of the variables used in the conventional fuzzy controller based on the magnitude of the error. A simulation analysis of the fuzzy controller and the adaptive fuzzy controller are don...

This paper aims to develop the 42V BLDC fan motor for hybrid electric vehicle using metal powdered core. So, the influence on a motor design by metal powder is described and the powder is applied as a direct replacement of lamination core. This point is focused upon a comparison of brushless dc motors, built with a powdered stator and Si laminated stator, which also has been redesigned to take ...

This application report discusses the most important issues concerning the use of TMS320 DSP-based systems in motion control. Motion control systems using fixed and floating-point processors are compared. Typical applications and experimental results are presented for schemes employing all common types of electric motors DC, induction, brushless, and step. This document was part of the first Eu...

Brushless DC motors play a vital role as workhorse in many applications, especially home appliances. In the competitive world of day, brushless motor is wise choice for applications because its high power density, simple driving circuit, and efficiency. Accordingly, demonstrating feasibility new controller on this type has undoubtedly paramount importance. Two methods speed controllers, namely ...

Brushless DC Motors have a permanent magnet rotor and the stator winding are wound such that the back electromotive force (EMF) is trapezoidal. The motor posses high Torque/weight ratio, operate at very high speed, very compact & electronically controlled. In this paper, we have to use three algorithms ZN, GA & PSO respectively. On the basis of performance of these three techniques, PSO have hi...

This paper presents the current work progress of HIT/DLR Dexterous Hand. Based on the technology of DLR Hand II, HIT and DLR are jointly developing a smaller and easier manufactured robot hand. The prototype of one finger has been successfully built. The finger has three DOF and four joints, the last two joints are mechanically coupled by a rigid linkage. All the actuators are commercial brushl...

The main objective of this research paper is to deliver the selection criteria of PMBLDC Motor for certain industrial applications. In general, Industries uses large Horsepower (HP) Brushless DC Motors as the special drives. These motors offer low starting currents with high starting torque, and the ability to supply reactive KVA to the plant system if desired. For specific industrial applicati...
