Abstract:

The dynamic model of agile missiles is developed. The force and torque amplification factors are used to describe the influence of jet interaction for the missile. For the direct force / aerodynamic compound control model, adaptive control allocation based on model reference is presented. In order to simplify the design, the strategy of weighted allocation is introduced, which can make the hybrid control system decompose into two subsystems, aerodynamics subsystem and direct force subsystem, respectively. The weighting factors are selected by using a genetic algorithm (GA) to optimize the multi objective cost function. The simulation results show that the designed blended control system can track the input command rapidly and implement the acceleration allocation between direct force and aerodynamic force.
