In this manuscript, a new method is proposed to provide a perfect tracking of the supercavitation system based on a new two-state model. The tracking of the pitch rate and angle of attack for fin and cavitator input is of the aim. The pitch rate of the supercavitation with respect to fin angle is found as a non-minimum phase behavior. This effect reduces the speed of command pitch rate. Control...

| In this paper, we investigate the noise suppression performance of a novel adaptive lter based on sub-space methods. In contrast to conventional subspace lters, this approach requires no eigenvalue or singular value decomposition. Therefore, our adaptive subspace lter can be implemented for real-time operation using general purpose digital signal processors. In addition, only the noisy signal...

A new method for the determination of electric signal time-shifts is introduced. As the Kolmogorov-Smirnov test, it is based on the comparison of the cumulative distribution functions of the reference signal with the test signal. This method is very fast and thus well suited for on-line applications. It is robust to noise and its performances in terms of precision are excellent for shift times ...

PAPR reduce the efficiency of system in MC-CDMA so we have to use PTS to recover from this. In this paper, Partial Transmit Sequence technique is used, which uses suboptimal algorithms & their performances are compared. For their performance evaluating PAPR reduction scheme is CCDF of the PAPR of transmitted continuous time signal. BPSO has better PAPR reduction capability than BFO Algorithm on...

In this paper, we solve the tracking and disturbance rejection problem for fully actuated passive mechanical systems. We assume that the reference signal r and its first two derivatives ṙ, r̈ are available to the controller and the disturbance signal d can be decomposed into a finite superposition of sinewaves of arbitrary but known frequencies and an arbitrary L2 signal. We combine the internal...

An adaptive servomechanism is developed in the context of the problem of approximate or practical tracking (with prescribed asymptotic accuracy), by the system output, of any admissible reference signal (absolutely continuous and bounded with essentially bounded derivative) for every member of a class of controlled dynamical systems modelled by functional differential equations.

A strategy to increase the robustness of active MR tracking of microcoils in low signal-to-noise ratio conditions was developed and tested. The method employs dephasing magnetic field gradient pulses that are applied orthogonal to the frequency-encoding gradient pulse used in conventional point-source MR tracking. In subsequent acquisitions, the orthogonal dephasing gradient pulse is rotated wh...

maximum power point tracking controller is essential to obtain the maximum power from a solar array in the photovoltaic systems as the pv power module varies with the temperature and solar irradiation. in this paper, several methods for the mppt of the pv systems are discussed and it can to be used as a helpful reference for the upcoming mppt user in the pv applications.

We consider the so-called generative systems used in tracking control problem. propose an algorithm for designing a linear dynamic system of required dimension such as its output is equal to reference signal with given accuracy. approach matching model and object which are not general case. The results illustrated by examples.

Monopulse radarsare one of the most accurate tracking radars used to guide various platforms. Detection and tracking of surface targets with these radars are performed in order to point strike targets. Sea clutter presents challenges for detecting floated targets and in addition to affecting detection height, it can cause errors in monopulse angle finding. In this paper, the airborne monopulse ...
