Research on Autipilots of Missile based on Multi-sampling Rate Digitial Control

When the missile guidance and control law is implemented in a specific hardware platform, different sampling frequencies occur among the guidance and control components due to the limitation of hardware performance. However, the current missile guidance control law design ignores this problem. This paper comparing the performance of classical control theory and multi-sampling rate control theory in missile platform by testing the response speed and accuracy in serval control channels, simulation results show that the multi-sampling rate control method has obvious advantages over the traditional method.
