In this paper, global exponential stabilization for chaotic brushless DC motor(BLDCM) is described. Based on Lyapunov theorem and stability theory, we design two controller to realize the global stabilization of BLDCM with exponential convergence rate. Numerical simulations suggest that the motor with the two controllers can converge efficiently.

This paper presents a novel matrix converter based topology with less number of semiconductor switches. The proper switching sequence of matrix converter is used to drive BLDC motor directly from single phase without dc link capacitor. A matrix converter fed BLDC motor is simulated in MATLAB. The proposed technique is simple to implement and cost effective. Keywords— Permanent magnet (PM), Brus...

A new permanent-magnet (PM) hybrid brushless (PMHB) machine is proposed and implemented as the integrated starter–generator (ISG) for hybrid electric vehicles (HEVs). It has the advantages of higher torque density than other PMHB machines and much wider speed range than other PM brushless machines. The key is to tune its dc-field winding current in such a way that three major modes of ISG syste...

Despite many advantages of BrushLess DC motor, torque pulsation is one of the most important disadvantages of it. At first, an optimum primary design of BLDC motor is done using PSO algorithm. Then, other parameters for reducing the torque pulsation are considered by finite element method. It is shown that fractional slot structure has many advantages than conventional one. Both cogging and rip...

in the permanent magnet linear synchronous motor (pmlsm), force ripple is harmful, useless and disturbing. the force ripple is basically composed of two components: detent force and mutual force ripple. this force is influenced by the geometric parameters of the permanent magnet (pm) motors; such as width, thickness and length of the magnet poles, length and thickness of the rotor and stator, a...

this paper presents the method of reducing torque ripple of brushless dc (bldc) motor. the commutation torque ripple is reduced by control of the dc link voltage during the commutation time. the magnitude of voltage and commutation time is estimated by a neural network and optimized with an optimization method named particle swarm optimization (pso) algorithm analysis. the goal of optimization ...

The paper describes an electronic multiprocessor system that assures functionality of a miniature UAV capable of 3D flying. The apparatus consists of six independently controlled brushless DC motors, each having a propeller attached to it. Since the brushless motor requires complex algorithms in order to achieve maximum torque, efficiency and response time a DSP must be used. All the motors are...
