A model for the simulation of the Mars EDL process

In order to analyse the influence of the control operation during the soft landing on Mars and design the control operation, this paper designs a model to simulate the EDL process (i.e., entry, descent and landing) of the space probe, and uses the computer numerical simulation method to simulate. Its main advantage is that it can accurately analyse the impact on various control operations on the overall mission design, which can more intuitively to help aerospace personnel design control schemes for computer numerical simulation in actual engineering tasks. The detailed derivation process is given. The simulation results show the validity and practicability of the model.
