Huang Shu and Tongwen Chen Dept. of Electrical and Computer Engineering University of Calgary Calgary, Alberta, Canada T2N 1N4 [email protected] [email protected] Abstract For a single-machine, in nite-bus power system, several digital robust stabilizers with single-rate and multirate sampling schemes are designed using modern H1 optimization. The digital stabilizers designed have low ...

An adaptive inferential algorithm is developed for estimation and control of multirate systems. The output y is measured J times slower than the secondary process output v and the input U, but an output estimate ye is produced at each sampling interval of v and U. Compared with previous work on multirate inferential systems, the proposed algorithm has a more formal theoretical basis. For exampl...

The unique capability of the Unified Power Flow Controller in multiple line compensation are integrated into a generalized power flow controller that is able to maintain prescribed and independently controllable, real power and reactive power flow within the line. We demonstrate the proposed technique on a single machine infinite bus system. In this paper, we propose UPFC with PSS design scheme...

Sampling rate conversion in multirate filter banks leads to time-varying phenomena, which differ between deterministic and stationary random signals. More specifically, downsampling causes deterministic signals to become periodically shift variant, while upsampling turns stationary random signals into cyclostationary signals. We provide criteria for the quantification of these effects, and comp...

In most chemical processes only some measurements are available online while other measurements are available infrequently and often with long delays. Multirate state estimation can optimally combine these different classes of measurements to improve the estimation quality compared to the fast measurements alone. The nature of measurements at different sampling intervals which are subject to de...

In many industrial control applications the control action updating can be faster than the output measurement, leading to multirate (MR) controllers. In this paper, the controller design is approached based on the characteristics of each available sampling rate. The controller is split into two parts acting at different sampling rates. By the lowest rate sub-controller the main points of the de...

Paper Presents Systematic VLSI design of Low Power and Area using Multirate digital signal processing system. This technique is necessary for systems with different input and output sampling rates, as the proposed multirate device is up sampler; FPGA implementation of the same is presented. The FPGA synthesis results are verified and report is presented. In order to build up sampler consisting ...

FREQUENCY invariant beamformer (FJB) is a beamA former in which the response is (approximately) constant over an arbitrarily wide design bandwidth. This type of beamformer is particularly useful in speech acquisition with microphone arrays, and several methods of design have been proposed [1]-[3]. In [4], a new analog technique based on approximating an ideal continuous aperture was presented. ...
