However, power electronic loads, when tightly regulated, sink constant power from the system. Therefore, they have negative incremental impedance characteristic. This can even cause negative impedance instability. Power electronic loads usually have a controlled or uncontrolled rectifier at the front end. In this paper, these loads are modelled using the generalized state space averaging method. An assessment of their effects in AC distribution systems is also presented.","PeriodicalId":345608,"journal":{"name":"IECON'01. 27th Annual Conference of the IEEE Industrial Electronics Society (Cat.

The system is a DC to DC LCC resonant converter whose switching frequency is tuned at the natural resonant frequency where the converter tends to act as a current source. In this way, two effects are achieved: (1) the necessary over-voltage, first to ionize the dielectric and then to establish the electric arc is generated, and (2) a constant current is supplied during the erosion of the workpiece, providing the circuit with inherent protection under short circuit conditions. The output voltage is intended to be adjusted by an external system that controls the arc distance.","PeriodicalId":345608,"journal":{"name":"IECON'01. 27th Annual Conference of the IEEE Industrial Electronics Society (Cat.

A new and promising use of networks is in the area of high performance control and automation, which is developing into attractive and widespread applications. Some of the major concerns in using networks to perform remote network-based control are QoS issues such as time delay and bandwidth constraints. Disturbances and unanticipated events often happen to network-based applications. When anomalies happen, if the network cannot provide the required QoS, the application may have to lower its performance requirement and use the assigned QoS to do the best as it can to maintain the application availability. This paper proposes the use of real-time application gain adaptation to compensate for QoS variations and deterioration. A numerical and an experimental simulation of a network-based controlled DC motor are used in this paper to illustrate the effectiveness of the proposed scheme.","PeriodicalId":345608,"journal":{"name":"IECON'01. 27th Annual Conference of the IEEE Industrial Electronics Society (Cat.

The method presents an on-line slip gain estimation algorithm to overcome the parameters' variation effect when computing the slip speed. The slip gain estimation uses short duration pulses added to the constant flux current. Based on the resultant torque command produced by the speed controller, the slip gain is properly adjusted. Simulations firstly verify the proposed estimation method. Also, a prototype DSP-based experimental system is built to demonstrate the feasibility of the proposed method.","PeriodicalId":345608,"journal":{"name":"IECON'01. 27th Annual Conference of the IEEE Industrial Electronics Society (Cat.

It is based on a single-ended primary inductance converter (SEPIC) operating in the discontinuous conduction mode. In this operation mode, it approximates a voltage follower and the line current follows the line voltage waveform to a certain extent. The reduction in low-order harmonics and improved displacement power factor is achieved without the use of any voltage or current sensors. The simplicity and reduced parts count of the proposed topology make it an attractive low-cost choice for many variable speed drive applications.","PeriodicalId":345608,"journal":{"name":"IECON'01. 27th Annual Conference of the IEEE Industrial Electronics Society (Cat.

For example, the power flow is essentially restricted by a line inductance. The author has proposed the variable active-passive reactance (VAPAR) which can produce a virtual variable inductance. The author analyzed the transient power flow of a balanced three phase variable inductance and obtained interesting results. In this paper, at first, the analysis of the instantaneous power of a power circuit including a three phase variable inductance is introduced using instantaneous active and reactive power theorem. Then, the power characteristics of three phase inductance with mutual variable inductance is analyzed. In this section, the concept of \"anti-mutual inductance\" of which mutual induced electromotive force appears in opposite direction to usual mutual inductance is proposed. The interesting characteristics of anti-mutual inductance is analyzed using instantaneous power theorem. The theoretical analyses are verified through simulations and some of them are verified through experiments.","PeriodicalId":345608,"journal":{"name":"IECON'01. 27th Annual Conference of the IEEE Industrial Electronics Society (Cat.

A disturbance compensation problem is solved by a fuzzy logic system (FLS) with adaptive positions of output fuzzy membership functions. The stability of the adaptation procedure is given via the Lyapunov stability theorem. FLS is divided into three fuzzy subsystems according to the physical properties of robot dynamics. This structure results in a clear fuzzy rule base with a reduced number of rules and enables systematic inclusion of linguistic knowledge. Performance of the proposed method is illustrated by experimental results in a motion control task and positioning task with varying payload on a three degree of freedom direct drive robot.","PeriodicalId":345608,"journal":{"name":"IECON'01. 27th Annual Conference of the IEEE Industrial Electronics Society (Cat.

The paper presents a general theoretical framework of how robust controllers can be designed, taking into account the constraint on the control signal. The systematic design of a robust controller is illustrated in case of a vector controlled brushless DC motor drive, which is identified using advanced identification techniques. In order to enhance the dynamic performances of the designed control system, in case of limitation of the control signal, a gain-scheduled control strategy is considered. The robust stability of the gain-scheduled control system, considering the variation rate of the time-varying parameter is studied by linear matrix inequalities. The proposed robust controller design approach is verified by experimental results in case of a brushless DC motor drive, when the control algorithm is implemented on a DSP board.","PeriodicalId":345608,"journal":{"name":"IECON'01. 27th Annual Conference of the IEEE Industrial Electronics Society (Cat.
