DIFFERENTIAL SENSITIVE ELEMENT ON SAW WITH SMALL CHANGE OF FREQUENCY AND
PHASE CODING
Sergey V. Bogoslovsky

Results of researches of a new method (a method of the coordinated phase coding with small change of frequency) constructions of contactless passive gauges on superficial acoustic waves on the basis of dispersive lines of a delay and phase modulation are resulted. The suboptimum kind of the law of change of the phase, providing high sensitivity to deformation piezoelectric plate is defined. The offered approach provides high noise immunity, accuracy of contactless measurements at the increased radius of action. Physical restrictions on realization of the offered methods are considered.

Habeeb Olalekan Aro
57
In this paper, the application of robust methodology for attitude stabilization of a sounding rocket is addressed. The unknown uncertainties are bounded and estimated. Stabilizing controller based on H-infinity optimisation and μ synthesis and analysis methods is designed while estimating the uncertainty model. The stability and performance levels of the control system are investigated at each estimate using computer simulation.
SEMI-NATURAL MODELING OF PLANE SYSTEM ANTI-SLIDING AUTOMATICS
Nadezhda A. Bogacheva, Alexey D. Zhukov, Sergey A. Zhukov
62
The questions connected with creation of the semi-natural bench, the plane simulating spatial land movement are considered. Function charts of a small contour of control - systems anti-sliding automatics - and the big contour of control - the plane as a whole are resulted. All basic forces and the moments operating on it at landing (take-of) are considered.
66
The new method of a nonparametric adaptive optimum filtration of the discrete signal observed against additive, generally, of the correlated hindrance of measurement is considered. It is supposed that the measurement model is linear, the signal and a hindrance are not correlated. As the aprioristic information matrixes of the moments of the second order of a vector of a hindrance and measurement model, and also approximate value of an interval quasi-stationary a signal are used.
