This algorithm has two stages. In the first stage maximum torque is achieved with optimal currents and voltages for any given speed, resulting in high efficiency. In the second stage, in the steady state, the controller corrects itself for stator resistance variations, thereby achieving robustness in the control scheme. The direct torque control implementation eliminates the need for vector transformations and results in a quick response making it suitable for a wide variety of applications such as electric vehicles (EYs). Simulation results show the performance of the proposed robust torque control scheme in response to high-speed demands and stator resistance variations.","PeriodicalId":166431,"journal":{"name":"2003 IEEE International Symposium on Industrial Electronics ( Cat.

The proposed circuit is an extension of the boost interleaved converter, incorporating a multistage capacitor multiplier. A simple nondissipative snubber can be used reducing the reverse recovery current of the diodes and also obtaining low turn-on and turn-off losses. The modularity of the structure allows the increment of the current, voltage and power levels, using the same range of components and maintaining high efficiency, only increasing the number of series and parallel stages. The paper gives a theoretical analysis, and experimental data on a 400 W example that was built and tested: 24 Vdc input, 200 Vdc output, and 40 kHz switching frequency. The measured performance agreed well with the theoretical predictions and the measured efficiency obtained is equal to 95% at full load.","PeriodicalId":166431,"journal":{"name":"2003 IEEE International Symposium on Industrial Electronics ( Cat.

Recently, the contribution of the output capacitor to the PFC system stability is highlighted. Therefore, in this issue the design steps are discussed depending on the three choices, output ripple, hold-up time and stability. It is clear that any design must take the minimum required storage capacitor as step-1 in the design and then apply for any other specification like hold-up time or ripple percentage.","PeriodicalId":166431,"journal":{"name":"2003 IEEE International Symposium on Industrial Electronics ( Cat.

A popular approach is to inject electrical current and then from measurements of the resulting boundary voltages to reconstruct a cross-sectional image representing the distribution of materials in the vessel. In many cases the process takes place in a hazardous environment and consequently there is a need for certified safe equipment. This paper reports on the design, construction and testing of the worlds first intrinsically safe electrical tomography system. To achieve certification zener barrier diodes and intrinsically safe relay- modules provide electrical isolation from the hazardous environment.

Among them, generalized predictive controller (GPC) has been proposed by Clarke, el al. Especially, since the GPC is designed based on multi-step prediction, it is well known that the GPC is effective for systems with ambiguous time-delays and/or time-variant time-delays. On the other hand, most real systems have uncertainty, and self-tuning controllers and robust controllers are proposed to cope with such uncertainties. According to the self-tuning control scheme, the stability is not necessarily guaranteed in connection with the convergence of estimated parameters. Moreover, in robust control, the control system becomes quite conservative, and tracking properties are not good. In this paper, a new design scheme of robust self-tuning 2-degree-of-freedom GPC. That is, the closed-loop controller is designed so that the robust stability is satisfied, and the pre-filter is designed to improve the transient response in an on-line manner. According to the newly proposed control scheme, the transient property for the set point response can be improved keeping the robust stability. Finally, the proposed scheme is numerically evaluate on two simulation examples.","PeriodicalId":166431,"journal":{"name":"2003 IEEE International Symposium on Industrial Electronics ( Cat.
