It normally involves a cut-and-trial process for a designer to come up with a proper filter design or approximation. As such, designing a filter is a time-consuming process for beginning engineers as well as for experienced engineers when they face new design circumstances. Due to this, predicting and solving EMI emissions related to common mode ones, induction motor drive systems require various frequency-dependent effects to be considered. Thus, the application of circuitry to increase the performance per size, prevent dependency on some parameters of the motor and the new conditions corresponding to the new technological improvements in our daily systems for an EMI filter is considered.","PeriodicalId":415046,"journal":{"name":"SICE 2001.

The control system is designed to maintain efficiency of motor by keeping the speed constant and the good transient response by using direct torque control. Fuzzy logic controller has been designed by genetic algorithm optimization technique as a means to determine and optimize the fuzzy logic controller design. In the proposed approach normalization factors and/or membership function parameters and/or the controller policy, are translated into bit-strings. These bit-strings are processed by the genetic algorithm and if the selection process as well as the objective function is chosen properly, a near-optimal solution can be found. To examine the efficiency of the proposed approach, a self-tuning fuzzy logic controller for direct torque control of the wound rotor induction motor drive is designed for the current in DC link circuit. A particular objective function is chosen to achieve a high dynamic performance. The simulation results demonstrate a significant enhancement in shortening the development time, and improving system performance over a conventional fuzzy logic controller.","PeriodicalId":415046,"journal":{"name":"SICE 2001.

The estimation performance is examined by comparing the pulse responses from the example system and the estimated model. The performance comparison of the proposed method and two existing techniques indicates that satisfactory parameter estimation is available from the proposed procedure. In addition, the role of sampling time and the aspect ratio of input pulse is examined and the noise robustness of the estimation in noisy process is investigated.","PeriodicalId":415046,"journal":{"name":"SICE 2001.

A new approach to the estimation of power system frequency using wavelet transform is proposed in this paper. This approach adopts a complex wavelet function as band pass FIR filters to estimate the instantaneous average frequency in its pass frequency band. Besides this, a recursive algorithm of continuous wavelet transform (CWT) based on polynomial type wavelet function is also presented, by which this wavelet approach is very suitable for real time implementation. The performance evaluation exhibits a high robustness and estimation accuracy of the proposed technique over a wide range of frequency deviation. It is further shown that this approach is capable of tracking power system frequency under dynamic conditions, and is immune to the effects of harmonics and decaying DC component.","PeriodicalId":415046,"journal":{"name":"SICE 2001.
