Abstract


Dummy can truthfully simulate various features of incoming missiles , air defense weapon system is developed , the design finalized flight test an indispensable equipment. In this paper, a certain type of ground missile attack in level flight segment and segment features as the main analog indicators , combined with the studied gliding extended target missile aerodynamic performance, its trajectory design and optimization, and expand the control system . First, create the corresponding coordinate systems, analysis Gliding Range dummy force suffered and external moment , get a complete mathematical model of the spatial six degrees of freedom . Gliding Range dummy according to the actual flight performance , make reasonable assumptions obtain longitudinal motion Gliding Range dummy model . For extended-range target missile unpowered gliding characteristics of the reference trajectory space cruise mode , that \to establish an improved scheme with falling angle limiting trajectory and the optimal combination of proportional navigation trajectory ballistic programs , and in the Matlab / Simulink environment established under the ballistic simulation model , complete trajectory simulation . Secondly, the use of small perturbation theory and the coefficient of freezing method, gliding extended range ballistic missile target linear differential equations , the establishment of the perturbation equations of motion derived elastomers transfer function , and on this basis , analyzes Gliding Cheng dummy longitudinal free dynamic perturbation motion stability and rudder deflection elastomer step maneuverability . Finally , according to the classical control theory, to determine Gliding Range dummy pitch angle and height of the control loop stabilization loop PID control structure, through frequency analysis method to complete the design of the control system . By the end Gliding Range dummy longitudinal control system digital simulation, verification of the designed controller and its parameters are reasonable.
