This paper describes an emotional controller for synchronous reluctance motor (SynRM) drive. The proposed modern controller is called brain emotional learning based intelligent controller (BELBIC). The utilization of BELBIC is based on the emotion processing mechanism in brain, and is essentially an action, which is based on sensory inputs and emotional cues. This intelligent control is inspired by the limbic system of mammalian brain. The proposed controller is successfully implemented in real-time through a PC-based three-phase, 0.5 Hp SynRM. In this work, the d-axis torque current and speed reference signals are accurately tracked. The performance of the proposed controller is compared with an optimized conventional PI controller in different operating conditions. The obtained results show superior proposed control characteristics, especially very fast response, simple implementation and robustness with respect to disturbances and parameter variations. This emotional intelligent controller consists of model-free simple structure with high auto learning feature, and therefore shows excellent promise for industrial scale utilization.

This article will begin by presenting two power take-off (PTO) technologies for the SEAREV wave energy converter (WEC) followed by the design methodology applied to electromagnetic generator cycles for the "all-electric" solution. We will describe the operating principle associated with the SEAREV WEC before discussing the two conversion technologies intended to transform wave energy into electricity. The types of systems are twofold: hydroelectric and all-electric. The strong coupling between the hydrodynamic, mechanical and electrical phenomena heavily influences the behavior of the recovery (PTO) system and leads to a complex system design that requires a full-scale modeling description. A unique design methodology for the all-electric conversion chain has been developed around several distinct control modes, including one featuring power leveling.

The asymmetrical three-phase induction machine fed by a single phase source, already discussed in previous work (L. Martins Neto et al., 1994), has nothing more than an ordinary squirrel cage motor. These windings have the ordinary spatial design with a displacement of 120° between them, but with a different number of turns in each phase. With a proper relation of number of turns in each phase and with the help of a capacitor connected between phases B and C, it is possible to make the induction motor produce nominal power at nominal speed. This research had the following structure: discussion of the mathematical modeling, study for the minimization of the oscillating torque, starting time, etc., and presentation of results through digital simulation and performance comparison with a similar symmetrical induction motor. Digital simulation takes into account time and space harmonics for the symmetrical and asymmetrical induction motors
