Abstract:

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

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.

The presence of faults in a system leads to a lower value for efficiency, accuracy and speed, and, in some cases, even a complete breakdown. Thus, early fault detection is a major factor in efficiency and productivity of the procedure.

The current work presents an efficient and novel observer design capable of stabilizing the residue and dynamic error for the nonlinear Lipschitz systems with faults as well as a troubleshooting analysis and determining the formation of secondary faults

The movement of the carrier and external factors (the effects of the atmosphere, temperature and pressure) degrade significantly the image quality of the servo optoelectronic systems (OES) and the positioning accuracy of the emitting OES. The issues of image quality improvement and the probability of keeping the image of the observation object (OO) on the optical axis of the servo EOS are considered.Materials and Methods. The development of an automatic control system for an optoelectronic device (ACS OED) involved solving a multi-criteria optimization problem taking into account

Abstract:

Angular rate sensors are widely used in various technology areas, especially in aviation and rocket technologies. Angular rate sensors are installed in aircraft stabilization, orientation and navigation systems to determine the object angular position and control. In addition, they could be introduced in the automatic control systems of a moving object to enter a signal proportional to the angular rate in the control function or to damp the object oscillations occurring under the action of angular or linear overloads. Various design schemes of angular rate sensors are currently known to perfor

This paper proposes a stable adaptive fuzzy control scheme for a class of nonlinear systems with multiple inputs. The multiple inputs T-S fuzzy bilinear model is established to represent the unknown complex systems. A parallel distributed compensation (PDC) method is utilized to design the fuzzy controller without considering the error due to fuzzy modelling and the sufficient conditions of the closed-loop system stability with respect to decay rateαare derived by linear matrix inequalities (LMIs). Then the errors caused by fuzzy modelling are considered and the method of adaptive control is u

Abstract:

Dynamic surface control (DSC) is a recognized nonlinear control approach for high-order systems. However, as the complexity of the system increases and the first-order filter (FOF) is introduced, there exists a singularity problem, i.e., the control input will reach infinity. This limits the application of the DSC algorithm to a class of real-world systems with complex dynamics. To address the problem of singularity, we present a novel DSC approach called nonsingular dynamic surface control (NDSC), which completely avoids the singularity problem and significantly improves the overall control p

In this paper, a semi-global trajectory tracking control scheme is proposed for quadrotor unmanned aerial vehicle (UAV) under time-varying input delays, input saturations, and bounded disturbances. Initially, in order to ensure the desirable control performance that tracking error is limited in a prescribed bound, an error transformation function is presented to transform the constrained problem into a stabilization one. Then, under backstepping control scheme, a state prediction method combined with a dynamic surface control (DSC) is presented to compensate for the effects of input delays, an

Summary statistics indicate that gold is observed to have the greatest stability in prices whereas crude oil has been most volatile. The unit root tests confirmed that in their original form all three commodities are non-stationary but become stationary after first differencing hence implying similar integration properties.
