In a generator of given rating, the weight and size of the system affect the fuel consumption directly therefore, power density is one of the most important issues in a stand-alone generator. The optimal current waveform for maximizing power density and minimizing machine size and weight in a nonsinusoidal power supply system has been proposed and verified by simulation and experiment. Also, a new simple algebraic method has been proposed to accomplish the proposed control without a FFT which is time consuming and complicated.","PeriodicalId":403239,"journal":{"name":"IECON'03. 29th Annual Conference of the IEEE Industrial Electronics Society (IEEE Cat.

In this paper, to overcome the performance degradation due to transport delay, we have used a memoryless controller.

In many robotic systems, the compliance or elasticity such as harmonic drive gears , deflection of links, flexibility of joint shafts and so on, is present. In the proposed approach, such torsional deformation due to naturally existing compliance or elasticity are positively utilized into the null space motion of the redundant manipulator. The total deformation at the end-effector can be precisely estimated in real-time by comparing internal position sensor with real position which is measured by optical sensing. By using this measured deviation, the natural compliance can be virtually amplified to realize a compliant null space motion. The validity of the proposed method is confirmed by several experimental results.","PeriodicalId":403239,"journal":{"name":"IECON'03. 29th Annual Conference of the IEEE Industrial Electronics Society (IEEE Cat.

Two control methods and the related compensation characteristics of a series active filter connected to the neutral conductor are presented in this paper. The distinct functions of the proposed active filter are mitigation of 3rd-harmonic voltage and neutral current in a three-phase four-wire distribution system in a building. The required power of the proposed active filter is less than 10% of that of the harmonic producing loads. A control method of the dc capacitor voltage on the active filter circuit is also described. it is clarified through experiments that one those two functions of the active filter can be realized selectively and the dc capacitor voltage of the active filter can be regulated to a desired value.","PeriodicalId":403239,"journal":{"name":"IECON'03. 29th Annual Conference of the IEEE Industrial Electronics Society (IEEE Cat.

For any periodic system, the balance must be occurring in every period, and for any disturbance which occurs the system must operate in the direction of damping this disturbance. One of the most practical examples is the boost PFC converter with average-current-mode control. It is suitable structure to draw input current with a near unity power factor. The main feature of this circuit is the bulk capacitance and using two control loops and multiplier in control circuit that assures its nonlinearity. PFC stability is interpreted as a condition in which the system operating in the expected periodic regime. Then, all those Subharmonic, quasi-periodic, period doubling, chaos considered undesirable and should be avoided. Two nonlinear phenomena are counted in PFC circuit, period doubling bifurcation (occurs first) and chaos. This paper addresses a study for the borderline between the stable and unstable regimes based on energy balance theory. The details of the proposed method are introduced and its validity is proved with simulation, experiment and mathematical analysis.","PeriodicalId":403239,"journal":{"name":"IECON'03. 29th Annual Conference of the IEEE Industrial Electronics Society (IEEE Cat.

For this purpose, this paper designs the robust feedback control system by using the coprime factorization and disturbance observer. The detecting signal of optical disk recording system is only a tracking error. Hence, the feedforward controller of the proposed tracking control system is constructed based on both \"zero phase error tracking\" (ZPET) control theory and prediction of tracking error. The experimental results point out that the proposed system has a quick and precise tracking response and keeps the residual tracking error below tolerance.","PeriodicalId":403239,"journal":{"name":"IECON'03. 29th Annual Conference of the IEEE Industrial Electronics Society (IEEE Cat.
