A Novel Controller Based on Multi- Resolution Decomposition Using Wavelet Transforms
نویسندگان
چکیده
In this paper, a Wavelet Controller analogous to a Proportional-IntegralDerivative controller is proposed. The control strategy is based on the multi-resolution decomposition of error signal using Wavelet Transforms. The output from a system represents the cumulative effect of many underlying phenomena such as process dynamics, measurement noise, effects of external disturbances etc., which manifest on different scales. The wavelet decomposition, which represents the error signal at different scales, enables us to compensate for these uncertainties in the control design. The work presented here is a first step in this direction. Simulation results are shown to validate the control strategy.

متن کاملTexture Classification of Diffused Liver Diseases Using Wavelet Transforms
Introduction: A major problem facing the patients with chronic liver diseases is the diagnostic procedure. The conventional diagnostic method depends mainly on needle biopsy which is an invasive method. There are some approaches to develop a reliable noninvasive method of evaluating histological changes in sonograms. The main characteristic used to distinguish between the normal...
متن کاملReal-time Multi-resolution Decomposition of Degrading Fault Signals using Entropy measure
Trend identification in gradually degrading faults poses a challenge due to embedded local large data variations in signals, which sometimes can interfere with the gradual trend. This paper describes combining Multi-resolution Signal Decomposition (MSD) property and denoising effect of wavelet transforms with entropy measure to eliminate local high frequency variations and retain the gradual pa...

Motion compensated wavelet (MC-Wavelet) video coding provides high coding efficiency and robustness along with spatio-temporal-SNR-complexity scalability. Such schemes use a multi-resolution motion compensated temporal filtering (MCTF) decomposition along with the spatial wavelet transform to remove video redundancy. These multi-resolution transforms partition the spatiotemporal sequence-volume...
