In order to handle the uncertainties, the uncertainties are considered as disturbances. First, a disturbance observer is designed and the uncertainties can be rejected by subtracting these estimated values of disturbances from the plant input. Since the disturbance observer is a kind of low-pass filter, it has inevitably estimation errors. To get rid of the effects of these errors, the additional control should be applied. This additional control input is designed using adaptive control scheme. The unknown disturbance error bounds are estimated by adaptive parameter estimation methods and then the control input is calculated using these estimate values. But the control input needs to be switched on the sliding surface and provokes a chattering phenomenon. The control method suggested in this paper can, however, reduce the chattering phenomenon as small as possible by using large disturbance observer gain because the magnitude of the switching control input is dependent on the disturbance estimation errors which are decided by the accuracy of the designed disturbance observer.","PeriodicalId":403239,"journal":{"name":"IECON'03. 29th Annual Conference of the IEEE Industrial Electronics Society (IEEE Cat.

The ANN, when implemented by dedicated application-specific IC chip, permits simple, fast and reliable operation far exceeding the capability of digital signal processor (DSP). The network receives the voltage magnitude and angular position of the command space vector at the input, and generates the digital words for switching times at the output that are then converted to symmetrical pulse widths for the three phases through simple logic circuits and a single timer. Several alternative ANN topologies have been proposed after successful training, and their structures and performances have been compared. The ANN-based modulator was then incorporated in induction motor drive systems with rotor flux-oriented indirect vector control, and the drive performances were evaluated extensively. In all the cases, performances were found to be excellent.","PeriodicalId":403239,"journal":{"name":"IECON'03. 29th Annual Conference of the IEEE Industrial Electronics Society (IEEE Cat.

This method uses a residual signal constructed from the comparison between the supply current and the desired value. To evaluate its performance, we have compared it with the direct current control technique based on the classic demodulation. The PWM control technique adopted is based on two comparisons of a triangular high frequency carrier signal and the source harmonic current. This harmonic signal namely +v and its opposite value -v are used, at the same instant, in the comparison process to generate the gate signals for the semi-conductor devices. By using the averaging technique, the direct consequence of using this PWM technique is that the transfer function of the SPSAPF becomes a pure gain. Simulation results using power system blockset Toolbox PSB of Matlab show the performance of the new control algorithm for SPSAPF implemented with the PWM adopted and its capability to compensate harmonics and reactive power.","PeriodicalId":403239,"journal":{"name":"IECON'03. 29th Annual Conference of the IEEE Industrial Electronics Society (IEEE Cat.
