In the last few years several solutions belonging to this category have been proposed. They have different configurations and distinct adaptation mechanisms, properly chosen in each case. A new, general adaptation mechanism is presented in the paper. It is derived according to Popov hyperstability theory and is valid for any adaptive system belonging to this category, no matter what its configuration is. A general demonstration for the stability of these adaptive systems is given, using the Lyapunov stability theorem. This unitary approach allows an easier comparison and classification of different particular solutions. The paper focuses on two of the most used configurations. In the first solution the reference model is the motor and the adaptive one is a linear state observer, which, in particular, is an extended Luenberger observer (ELO). In the second solution, both models are rotor flux (or other quantities) estimators and this scheme is usually known as a model reference adaptive system (MRAS). The performance of these two schemes is analyzed starting from their configuration and then compared by simulations and experimental results.","PeriodicalId":177291,"journal":{"name":"IAS '96.

In previous work a noncirculating type of bearing current caused by parasitic capacitive coupling from stator windings to the rotor was identified. In this paper a new circulating inductive type of bearing current is reported. A theory for the existence of this new type of bearing currents in inverter-motor drives is proposed. It identifies the fact that unbalanced currents flow in the two coil sides of a motor winding due to distribution of capacitive coupling currents. The current unbalance produces a high frequency magnetic flux surrounding the motor shaft and thus causes a bearing current to circulate in the conductive loop formed by the stator case, rotor shaft and end bearings. The amplitude of the circulating bearing current depends on the common mode component of capacitive coupling currents. The analysis is verified by experimental measurement or bearing currents. The findings also provide insight to determining solutions for attenuating these destructive bearing currents.","PeriodicalId":177291,"journal":{"name":"IAS '96.

Normally the power consumption of an AC silent discharge is measured by using a wattmeter on the low voltage side of the input transformer. However, this measurement includes the transformer losses which generally are nonlinear and may account for a significant proportion of the total power loss. Alternatively, the power loss in the silent discharge alone may be calculated by means of results obtained from the oscillograms of the charge versus voltage (q-v trace) method or by sampling the discharge current and high voltage signals. However, the measuring accuracy of these methods is limited and they are not convenient for use in practice, This paper presents a versatile, automated system for power measurement in an AC silent discharge. The system combines high-accuracy A/D data acquisition technology with the q-v trace method. Experimental results and analysis are presented to show the improved accuracy, speed of response and convenience over conventional measuring methods. The method discussed here is applicable to the power measurement in similar discharges, such as AC corona discharges, etc.","PeriodicalId":177291,"journal":{"name":"IAS '96.
