Parameter design for a guidance and control system using genetic approach (Q2778687)

A preliminary guidance and control (GC) design for a guided missile via a genetic search approach is developed in this paper. The design is to find optimal control parameters, a proportional navigation gain \(N\), a guidance filter time constant \(t_g\), and an aerodynamic turning rate time constant \(t_a\). The problem is a constrained optimization one, where the cost function consists of final miss distance and a control energy consumption. In Section 2, a simplified missile GC system and a simplified homing loop are described. An inherent stability constraint is shown in Section 3. A preliminary parameter design using genetic algorithms is developed in Section 4, where a real-coded genetic algorithm that uses a floating point representation is developed. In Section 5, simulation results and the analysis are illustrated.
