Cooperative Guidance Law for Multiple Missiles with Limited Communication Data Rate

Considering the practical limited communication rate, it is both beneficial and necessary to introduce quantization and consider its corresponding influence in multi-missile cooperative guidance. In this paper, a quantized leader-follower cooperative guidance method is proposed to achieve quantized consensus, wherein the multi-missile system accomplishes cooperative attack at the desired time while reducing the communication data rate. The communication protocol is formulated based on the second-order coordination variable systems with partially measurable state. The dynamic non-uniform quantizer is adopted to optimize the quantization effect and obtain as few quantizer levels as possible. In addition, the convergence of multi-missile collaboration error is illustrated. Numerical simulation proves the validity of the proposed method.
