Abstract
A description is given of an application of a linear-quadratic regulator (LQR) for stabilizing the characteristics of an anti-aircraft missile, and an analytical method of selecting the weighting elements of the gain matrix in feedback loop is proposed. A novel method of LQR tuning via a single parameter ς was proposed and tested. The article supplements and develops the topics addressed in the author’s previous work. Its added value includes the observation that the solutions obtained are symmetric pairs, and that the tuning parameter ς proposed for the designed linear-quadratic regulator enables the selection of suitable parameters for the airframe stabilizing loop for the majority of the analytical solutions of the considered Riccati equation.
Highlights
A comparison of the guidance processes was made for the eight missile models using the feedback loop gain matrices given by Equations (25)–(28) with the tuning parameter values presented in Section 2.4
This paper has described the use of an adaptive linear-quadratic regulator to stabilize the static and dynamic characteristics of the airframe of a canard-controlled anti-aircraft missile
A procedure to determine analytically the entries of the feedback-loop gain matrix was outlined and a novel method of linear-quadratic regulator (LQR) tuning via single parameter ς was proposed and tested
