It has been previously demonstrated that an induction machine drive with contactorless pole changing can be achieved by reversing current directions of certain stator coil groups. This paper compares the power and torque capability of this drive with conventional four-pole and two-pole induction machine drives. Based on the technique of vector space decomposition, the machine coupled-circuit mo...

A physcial approach is employed to estimate the rotor flux for a position sensorless induction machine drive system. This approach i s based on the fundamental operating characteristics of the induction machine. The estimator structure calculates the rotor flux accurately at low speeds, and as laryely insensitive to parameter variations. System structure, theoretical analysis, simulation, and l...

Main flux saturation in induction machines plays an important role in a number of operating regimes and therefore has to be accounted for in the process of modelling. The current state space model of a saturated induction machine has gained substantial popularity recently as an excellent tool for transient and steady-state time domain analysis of induction motor drives when the main flux satura...

This chapter describes recent advances in genetic programming of machine code. Evolutionary program induction using binary machine code is the fastest known Genetic Programming method. It is, in addition, the most well studied Genetic Programming system that uses a linear genome. Evolutionary program induction using binary machine code was originally referred to as Compiling Genetic Programming...
