Abstract :
A terminal guidance law based on proportional navigation was presented for intercepting maneuverable target in intra-atmospheric space. According to the constructed model of the mass moment interceptor with three-axial stabilization, a nonlinear dynamic system was acquired. Taking the time-variant overloading into consideration, the attitude angles and overloading errors were used for the performance index. After the control parameters were optimized using genetic algorithm, the corresponding relation was founded between moving mass position and overloading, attitude angles. Simulation results show that the attitude stabilization can be satisfied to realize efficiently the terminal guidance of interceptor as well as precision demand
