This paper reports variants for checking the median error of the 2Е36 weapon stabilizer under conditions of a standard path by means of video recording with a film camera followed by film processing and performing all operations in a manual mode. A procedure of measuring the median error of the SVU-500 weapon digital stabilizer has been given. To ensure the possibility of determining the errors of stabilization in each set of stabilizers, the enterprise-manufacturer has devised and implemented for the customer's main product, without using a standard path, a new procedure for measuring a d

This paper formulates sufficiency-type linear-output feedback decentralized closed-loop stabilization conditions if the continuous-time linear dynamic system can be stabilized under linear output-feedback centralized stabilization. The provided tests are simple to evaluate, while they are based on the quantification of the sufficiently smallness of the parametrical error norms between the control, output, interconnection and open-loop system dynamics matrices and the corresponding control gains in the decentralized case related to the centralized counterpart.

Abstract:
We address the problem of dynamic output feedback stabilization at an unobservable target point. The challenge lies in according the antagonistic nature of the objective and the properties of the system: the system tends to be less observable as it approaches the target. We illustrate two main ideas: well chosen perturbations of a state feedback law can yield new observability properties of the closed-loop system, and embedding systems into bilinear systems admitting observers with dissipative error systems allows to mitigate the observability issues.

This paper is concerned with the stabilization problem of an optimal dynamic quantized system with packet loss. The optimal dynamic quantizer, which minimizes the quantized output error, is designed for a discretetime system with packet loss occurring in the forward channel. A sufficient condition for the system’s mean square stability is developed based on matrix inequality method. A state feedback controller design method is also proposed, and numerical simulation demonstrates the effectiveness of the proposed method.

A constraint violation stabilization method has been used to solve a mixed set of algebraic and differential equations formulated for the dynamic analysis of a constrained mechanical system. However, the absence of a clear-cut method for determining the feedback coefficients associated with this method makes it unattractive and unreliable for its user. This paper presents a method for determining the optimal feedback coefficients which minimize the propagation of constraint violation. This method is based on the stability analysis for the error propagation dynamics of the modified constrained

The single-factor method was adopted to study the influence of different initial compactness on the mechanical characteristics of ballasted bed during the dynamic stabilization unit operation.

The vessels are modeled as three degree of freedom planar rigid bodies with two actuators. Algebraic graph theory is used to model the network as a directed graph and employing a l

Abstract In this paper, a method of analyzing the performance loss caused by faults that effect the longitudinal control of an automated vehicle is presented. First, a hybrid longitudinal controller based on Dynamic Surface Control (DSC) is developed to provide robust stabilization. Then, ellipsoidal approximations of the tracking error bounds are obtained via convex optimization for the nonlinear closed-loop system. The bounds are then used to design a fault classification scheme and fault management system based on the amount of performance loss as measured by a quadratic Lyapunov function.
