The Scheme of decision and management system for combinational flight control with differential kinds of control effectors were proposed. The blended dynamic model of missile with aerodynamic fin, thruster vector control and side thruster was developed. The design scheme integrating control allocation with blended controller optimizing was proposed. Control allocation strategy based on fuzzy logic and model reference adaptive control was developed, which made the equivalent dynamics of the blended actuators between the aerodynamic fin, thruster vector control and side thruster equal to the one of the reference model. The parameters of the blended control system were selected by optimizing a multi-objective cost function using evolutionary strategies (ES). The simulations on different kinds of control combinations demonstrated the blended control system had strong abilities of tracking high maneuver acceleration command rapidly and implementing the adaptive control allocation among the aerodynamic fin, thruster vector control and side thruster with different combinations.
