    The design and implementation of a high performance induction motor servo drive system is presented. An experimental indirect field-orientated induction motor drive system is implemented, and its dynamic model is built up using stochastic techniques. To obtain good dynamic responses both in the position command tracking and load regulation characteristics, a position servo controller with two degr... View full abstract»

    Recent interest in the synchronous reluctance motor has increased in the context of possible applications in field oriented AC drives. The absence of rotor slip losses and the apparent simplicity of the control suggest the possibility of performance and cost advantages over the induction motor. With field oriented control, and continuous shaft position feedback, the synchronous reluctance motor do... View full abstract»

    A method to design an improved motor excitation for three-phase brushless permanent magnet motors is presented. The unique motor excitation reduces ripple in the developed torque, reduces the effects of cogging or detent torque, and is also a minimum average power excitation. Practical benefits are reduced vibration and acoustic noise in speed control applications, and improved accuracy in positio... View full abstract»

    The feasibility of applying rational methods of optimisation to a superconducting generator design is presented. A new design method is developed which permits the optimisation of a superconducting generator to take place. The method is used in a computer program software package which systematically determines the optimum design parameters of the machine components. The optimisation techniques an...

    A steady-state mathematical model for a general linear induction motor (LIM) is evaluated from a transient model based on complex phasor analyses. All basic parameters of a LIM such as pole pitch, airgap width, slot width, slot depth, winding pattern, etc. are incorporated into the model by means of efficient factors, most of them dimensionless. The influence of these parameters and/or factors on ... View full abstract»

    The authors report the development and implementation of an algorithm for the online timetable checking and rescheduling of the 50 Hz single-phase overhead current collection catenary system currently in operation in Hong Kong. Running as an online consultant on a personal computer, this algorithm allows operating personnel to perform checking of a proposed time table under various feeding conditi... View full abstract»
