Abstract
Several various missile homing systems (MHS) have been developed in recent years. However, to the best of our knowledge, these systems do not take into account the dynamic characteristics of the measurement elements (ME). Such existing systems can only work well when the MEs have a small inertia and large damping. Thus in general case, it is necessary to consider the dynamic characteristics of the MEs with the big inertia. In addition, using the MEs with the big inertia, the MHSs is able to remove the high-frequency noise. However, taking into account the dynamic properties of the MEs causes difficulties in determining the transfer function (PF) of the normal acceleration stability system and the synthesis of MHSs. Therefore, in this paper, we propose an effective mathematical model of the missile homing system, which takes into consideration the dynamic characteristics of the MEs. In addition, this model allows synthesizing the high accuracy MHSs, and utilizing the MEs with the inertia equivalent to the inertia of the rudder actuator. To accomplish that, the proposed system is composed of two stages. In the first stage, the MHSs, which do not incorporate the dynamic characteristics of the MEs, is presented in detail. Then, we analyze and estimate the effect of the dynamic characteristics of the MEs on the performance of the MHSs. In the second stage, we propose a novel MHS, which takes into account the dynamic characteristics of the MEs. The proposed system is implemented based on the basic functions in the Control system toolbox in MATLAB, and designed by the parametric optimization method. The simulation results indicate that, our proposed system outperforms the conventional MHSs in term of reducing the negative effects of the dynamic characteristic of the MEs on the quality of the MHS.
