Dynamics and Control of a Gyroscope-Stabilized Platform in a Ship Anti-Aircraft Rocket Missile Launcher

The paper presents the ways of stabilising and controlling a Ship Anti-Aircraft Rocket Missile Launcher (SAARML) with the use of a Three-Axis Gyroscope-Stabilized Platform (TAGSP). The analysis of the dynamics of the SAARML and TAGSP systems is conducted for the case of searching and tracking a manoeuvring air target in the conditions of interferences and the influence of kinematic forces from the base (ships deck). Some research results are presented in a graphical form.

An algorithm for selecting optimal controls to determine the estimators of the coefficients of a mathematical model for the dynamics of a self-propelled anti-aircraft missile system

Today’s self-propelled anti-aircraft missile systems are designed to intercept low-flying, manoeuvring targets not only under any weather conditions but also during movement of the carrier vehicle over rough terrain. As target search and tracking need to be reliable, i.e. not affected by unfavorable conditions, a self-propelled surface-to-air missile system requires suitable stabilization and control systems. This implies that it is necessary to develop an adequate mathematical model of the missile system dynamics. In this article, we propose a procedure for experimental design to determine the coefficients of such a model. Particular attention is paid to the algorithm for selecting optimal controls and a time-dependent measurement spectrum to minimize the assumed criterion of quality.

Adaptive control of anti-aircraft missile launcher mounted on a mobile base

This paper presents the problem of control of anti-aircraft missile launcher mounted on a moving carrier-vehicle. Direct excitations on the vehicle from the road cause adverse vibrations of the launcher. In order to increase the precision of the guiding system in the conditions of self-propelled movement of the setup on a bumpy road, the adaptive control algorithm was proposed. Some research results of computer simulation are presented in a graphical form.

Selected methods of control of the scanning and tracking gyroscope system mounted on a combat vehicle

Abstract At present, remotely controlled modules of weaponry are becoming the basic equipment of modern army. The device for searching and observing air targets is one of the most significant elements of a weapon module. The device of that type in the form of the scanning and tracking gyroscope system is considered in the article. The process of automatic search of a target is carried out during the movement of a combat vehicle as well as during its manoeuvres. After a target is detected, it is tracked till it has been destroyed by the fired missile. The algorithm of control of the scanning and tracking gyroscope system, mounted on the deck of a combat vehicle, was developed. The optimized, classic PD controller, fuzzy controller PD type, fuzzy controller PID type and adaptive fuzzy controller were designed. Numerical research of the dynamics of the controlled gyroscope system and the assessment of the quality of control were conducted. The results of research are presented in a graphical form.

Optimal Control of the Searching and Tracking Head (STH) for Self Propelled Anti Aircraft Vehicle

The paper presents an algorithm for controlling a searching and tracking head (STH) mounted on a mobile vehicle. A numerical analysis was conducted to establish the dynamics of the controlled STH due to the kinematic action of the vehicle moving over rough terrain. Some of the computer simulation results were represented graphically.

Mathematical Model of Movement of the Observation and Tracking Head of an Unmanned Aerial Vehicle Performing Ground Target Search and Tracking

The paper presents the kinematics of mutual movement of an unmanned aerial vehicle (UAV) and a ground target. The controlled observation and tracking head (OTH) is a device responsible for observing the ground, searching for a ground target, and tracking it. The preprogrammed movement of the UAV on the circle with the simultaneous movement of the head axis on Archimedes’ spiral during searching for a ground target, both fixed (bunkers, rocket missiles launching positions, etc.) and movable (tanks, infantry fighting vehicles, etc.), is considered. Dynamics of OTH during the performance of the above mentioned activities is examined. Some research results are presented in a graphical form.

An Inverse Dynamics Analysis of the Remote Controlled Artillery-Missile System Under the Influence of Disturbances

The paper presents a dynamic model of hypothetical missile-artillery system mounted on a moving object (e.g. mobile platform or warship). Model inputs are driving torques for the azimuth and elevation angle, and the angular and linear displacements of the set base relative to the given stationary coordinate system. The output of the model is the resulting position of the line of sight relative to the mentioned stationary coordinate system. The effect of disturbances (motion) from the moving object was studied and the reverse dynamic analysis of the presented system under the influence of the disturbances was performed. This has been investigated to check if the set’s drive systems will be able to work out the required torque in time to maintain the desired line of sight. Simulations were made using the SciLab environment. Some results of numerical simulation tests was presented in graphical form.

The paper presents elements of an analysis of reachability areas of manoeuvring air targets achieved by maritime missile-artillery system ZU-23-2MRE. A concept of a modified algorithm of missiles homing of such system is presented. On the basis of tactical and technical data concerning armament of the above-mentioned system and taking into account extremely unfavourable flight parameters of the tracked target, the starting zone and the zone of destruction possible to technical implementation for particular air-defence fire unit were.
