This paper presents 3D modeling of hysteresis motor with high temperature superconducting material in the rotor using Finite Element based solver software COMSOL Multiphysics. Due to the anisotropic property of HTS material, magnetic flux distributions are non-uniform in different axes. Therefore, analysis of HTS hysteresis motor using two dimensional modeling cannot provide high degree of accuracy...
Hunting is an important phenomenon where the speed of synchronous motor fluctuates slightly above and below the normal synchronous speed. This paper presents an investigation of hunting of hysteresis motor with high temperature superconducting element. Both loaded and unloaded conditions are considered for analysis. All the simulations are performed using Matlab/Simulink and COMSOL Multiphysics.
This paper introduces a bio-inspired meta-heuristic soft computing method to optimize the performance of a PID controller used in DC motor speed control. APID controller is designed for an adopted second order DC motor system and the evolutionary algorithm based on Grey Wolf Optimizer is used to optimize the controller. In MATLAB/Simulink environment, the best set of PID parameters thus obtained from...
