The power control of a novel fractional slot concentrated wound interior permanent magnet synchronous generator, directly driven by non-pitchable wind turbine emulator above base wind speeds is presented in this paper. The small scale fractional slot concentrated wound interior permanent magnet synchronous generator utilized has good flux weakening properties due to the interior permanent magnet rotor...
Most speed control algorithms for induction motors (IM) require at least two current sensors. Due to the fact that especially the speed sensor can be related to an increased fault probability and maintenance effort, speed-sensor-less control algorithms are applied for drive applications where corresponding dynamical deficiencies can be tolerated. In any case the current sensors are required to employ...
This paper proposes a discrete-time predictive controller for providing high performance speed control in an induction motor drive. Specifically, the conventional speed PI controller is replaced by a model predictive controller and the control law is derived by the optimization of an objective function that considers the reference and the real speed as well as the acceleration of the induction motor...
In this paper, a comparative study of speed control efficiencies based on two dynamical models is presented. The common structure of dynamical models is developed using first principles of physics. The complex thrust mechanism is studied using two different techniques. First, we apply a novel data-driven approach to build up the non-linear mapping between tail angular motion and thrust generated,...
