“…Actually, this issue is more critical for the surface-to-surface guided projectiles than the air-to-surface configurations due to the effect of the booster resulting high amount of linear acceleration [11,12]. In the sense of control of the guided projectiles, several schemes are developed regarding the effectiveness of the application [13][14][15][16][17]. In this extent, certain control approaches including robust algorithms are designed for the elimination of the diverting effects of the disturbances and noise [18,19].…”

Guidance munition has become one of the popular subjects in both the theoretical and applicable studies since they could find a wide field of use in recent years because of their high performance and lower collateral damage capabilities as per the improving defence concept. The use of smaller and lighter guided munition makes the stated advantages increase without relinquishing the effectiveness. In this study, the design of a guidance kit which makes the mortar projectiles become guided when released from aerial platforms and the relevant computer simulations performed upon a selected projectile model are investigated. Here, two different configurations are considered based on the rotational degree of freedom of a pair of fins mounted on a rotary ring. In the simulations in which it is assumed that the guided projectile is released from an unmanned aerial vehicle, the different values of the fin deflection, autopilot switching duration, and side wind are considered for both of the mentioned geometries. Finally, the final miss distance and time of flight values obtained for all the designated cases are compared.

“…In the 1950s, differential game theory was introduced with the development of maneuvering pursuit technologies in aerospace (e.g. guidance systems, satellite launches) [15], [16]. Then, scholars fused modern control theory with game theory and applied it to a two (multi-) party optimal control problem [17], [18].…”

This article proposes a robust control optimization design problem based on Nash game-theoretic for the marching tank bi-directional stabilization system of an all-electric actuator, which is accompanied by complex uncertainty (possibly fast time-varying but bounded). The task is to drive the barrel firing angle to adjust to a specified position under complex uncertainty while ensuring that multiple design parameters are optimally chosen in the controller. Firstly, the machine-electric coupled dynamics equations with uncertainty are created in the form of state space. Secondly, a robust controller with two design parameters to be chosen is given so that the constraint following error has uniform boundedness and uniform ultimate boundedness. Thirdly, a Nash game cost function consisting of three components: performance cost, time cost and control cost is proposed, and the Nash equilibrium (i.e., optimal control parameters) is obtained by minimizing the cost function. Finally, a co-simulation experimental platform is built to verify the robustness of the controller under complex uncertainty (modeling errors, uncertain disturbances and road excitation) and to demonstrate the global optimal performance of the system under optimal design parameters.

“…It is difficult to meet guidance accuracy requirements with the traditional guidance law, and so it is necessary to study new guidance methods in order to deal with current threats from the air. The proportional guidance method is widely used in weapons systems because of its simple form and easy implementation in engineering [3,4,5]. However, at the end of interception, the proportional guidance method is prone to overload saturation caused by the divergence of the line of sight rate, which leads to full deflection of the actuator.…”

In this paper, fractional-order calculus theory is used to investigate the geometric law for intercepting an agile target. In order to overcome the challenges presented by the divergence of line of sight rate (LOSR) of proportional navigation (PN), the fractional LOSR is used as a compensated term in the proposed fractional differential geometric guidance law (FDGGL). By adjusting the navigation gain of the FDGGL, the new proposed guidance law can be transformed into the traditional differential geometric guidance law (DGGL) and PN. The average overload and ballistic stability of the FDGGL are analyzed based on the fractional and control theory. Some analytical results about energy consumption and trajectory variation of the FDGGL were obtained. The simulation results shows that, compared with PN and DGGL, the FDGGL has better guidance performance when intercepting different maneuvering targets.
