Electromechanical guidance system based on a fuzzy proportional-plus-differential position controller

Abstract

Purpose. The purpose is to develop solutions for the implementation of optimal laws of arms positioning, overshoot-free and requiring no post-adjustments. Method. The control model is based on the fuzzy set theory; and the structural modeling methodology is used to study the dynamics indices. Results. The structural scheme of the positional electromechanical system with a fuzzy proportional-plus-differential position controller and the method of control adaptation to the position reference signal change are obtained. Scientific novelty. A model of a fuzzy proportional-differential controller signal adaptation in the structure of a positional electromechanical system is proposed. Practical value. A solution is obtained for the implementation of optimal guidance process, non-overshooting and requiring no post-adjustments, also featuring the maximum weapons speed and minimal sensitivity to parametric disturbances.
