The controller uses only the motor position and the yaw angle for feedback. The tracking error is shown to be globally uniformly bounded. Simulation studies are presented to validate the controller performance.","PeriodicalId":441363,"journal":{"name":"Proceedings of the 1999 American Control Conference (Cat.

A digital signal processor (DSP) is used to implement the sensorless scheme. The PMAC stator is wound like that of a conventional three-phase induction motor. Taps are also provided which are used for voltage measurements. By measuring the tap voltages, absolute position of the permanent magnet AC motor, driven by a current regulated PWM inverter, with a fixed frequency ramp comparison controller, is estimated. The estimated position information is independent of the stator resistance, thus this scheme is even applicable at low speeds.","PeriodicalId":441363,"journal":{"name":"Proceedings of the 1999 American Control Conference (Cat.

For the data analysis portion of the work, cell counts per unit time are done, and interarrival times between cells are determined. Source modeling is done for the two large variable bit rate users and a constant bit rate user from the data. From the empirical distribution of interarrival times, the source modeling is made by a sequence of pairs of random variables (X, Y) where X represents the cell bursts and Y represents the interarrival times between bursts. Within each burst, the distribution of cells is determined by a finite state Markov chain, and the interarrival times of the bursts are also determined by a different finite state Markov chain for two users. The model is validated by comparing the interarrival times of the model and of the trace data. The analysis of the queue in the buffer is done; quantiles of the tail of the queue are also determined, as well as mean cell delays and cell loss ratios.","PeriodicalId":441363,"journal":{"name":"Proceedings of the 1999 American Control Conference (Cat.

An analysis of the effect of parameter perturbations on the stability of input-state linearizing controllers that make use of a state estimator, is presented.","PeriodicalId":441363,"journal":{"name":"Proceedings of the 1999 American Control Conference (Cat.

However, recent changes to the building codes have made the design requirements such that some of the potential gains of such systems may not be realized. This paper investigates the effects of using controllable semi-active dampers, such as magnetorheological fluid dampers, in a base isolation system. A two degree-of-freedom model of a base isolated building is used, with linear viscous, active, and semi-active supplemental damping devices in the isolation layer. Using an H/sub 2//LQG control design, semi-active and active devices are able to achieve a notable decrease in base drifts, compared to the optimal linear passive designs, with no accompanying increase in accelerations imparted into the superstructure.","PeriodicalId":441363,"journal":{"name":"Proceedings of the 1999 American Control Conference (Cat.
