“…The concept of efficient control has been implemented using different strategies [13], and can be classified into search control (SC) [14][15][16][17][18][19][20] or loss model control methods (LMC) [7,[21][22][23][24][25][26]. Regardless of the approach, the strategy to improve the efficiency is typically based on decreasing the magnetic flux in the machine at light loads to reduce the losses at the expense of a slower dynamic response.…”

“…To construct the model it is necessary to know the machine parameters, and this constitutes the main weakness of the method since it becomes sensitive to parameter detuning. When the theoretical model is simple the optimal flux can be analytically obtained [21], whereas no analytical techniques can be used when the complexity of the model increases [7,[22][23][24][25][26].…”

Abstract-The redundancy of multiphase drives provides an inherent fault-tolerant capability that is appreciated in applications with a complicated corrective maintenance or safety-critical requirements. Fault restrictions however force the system to be reconfigured to operate in a smooth and efficient manner. Previous works have been focused on the optimization of current waveforms to generate an undisturbed operation but still maintaining the pre-fault rated flux settings. This work shows that efficient controllers can improve the post-fault performance in six-phase induction machines supplied by parallelconnected converters if offline optimization is used to obtain a variable reference flux. Theoretical and experimental results confirm that the proposed flux adaptation method provides higher torque/power capability, lower degree of imbalance in the current sharing between windings and efficiency improvement.

Abstract-Due to robustness, reliability, low price and maintenance free, induction motors (IMs) used in most of the industrial applications. The influence of these motors (in terms of energy consumption) in energy intensive industries is significant in total input cost. This paper presents a review of the developments in the field of efficiency optimization of three-phase induction motor through optimal control and design techniques. Optimal control covers both the broad approaches namely, loss model control (LMC) and search control (SC). Optimal design covers the design modifications of materials and construction in order to optimize efficiency of the motor. The use of Artificial Intelligence (AI) techniques such as artificial neural network (ANN), fuzzy logic, expert systems and nature inspired algorithms (NIA), Genetic algorithm and differential evolution in optimization are also included in this paper. Experimental and simulation examples on efficiency optimization are illustrated.

SUMMARYA new, precise vector control algorithm for the current source inverter (CSI) fed induction motor drive is presented. The goal is to obtain the same performance that exists in PWM vector controlled drives. For that purpose, the problems of the existing vector controlled CSI fed induction motor drives are analyzed with the help of an adequate simulation model. For verification of the suggested algorithm, the prototype of the drive is developed. The frequency converter is a standard thyristor CSI and the complete control is implemented by software in the microcontroller. By eliminating the phase angle error and correcting the error of current magnitude the algorithm proposed in this paper can improve the dynamic performance of the CSI fed induction motor drive. The simulation and experimental results confirm the advantage of the proposed algorithm.
