A description is given of an application of the sliding mode control (SMC) for stabilizing the static and dynamic characteristics of an anti-aircraft missile. The solution provides effective separation of the control process from the dynamics of the missile airframe. In the equivalent part of the stabilization system, a linear-quadratic regulator (LQR) is considered, and an analytical method of selecting the weighting elements of the gain matrix is proposed. This eliminates the need for an iterative solution of the Riccati equation. A nonlinear switching component is introduced into the control signal to provide smoothness of the system response. In simulation tests, the proposed solution was evaluated against selected quantity indices. The paper ends with observations and conclusions.

This paper examines a linear-quadratic stabilization system for a canard-controlled missile. An analytical method for selecting the weighting elements of the gain matrix in the feedback loop is also proposed, eliminating the need for an iterative solution to the Riccati equation. The proposed solution was evaluated using simulation tests.

Theoretical considerations and a simulation study concerning description and analysis of new autopilot structures and issues relating to conversion of guidance commands into deflections of a complex system of control surfaces aimed at minimizing the miss distance value are presented in this paper. Due to nonlinear and nonstationary nature of the phenomena associated with the guidance process, a significant role is assigned to simulation studies. A comparative analysis has been made of the guidance processes of three models of a dual-control missile, which differ in terms of formulae implemented in the control command converters.
