System Identification of an Aerial Delivery System with a Ram-Air Parachute Using a NARX Network
Round 1
Reviewer 1 Report
The paper is a well written piece of work, however some issues shall be pointed:
- The model does not consider any wind of turbulence. This may seem unrelevant but it is critical from the point of view of a realistic application of the method. With no wind, the inertial sensors perfectly captures the dynamics of the system, so the parameter stimation process is straightforward.
- The values for the estimated parameters shall be indicated and discussed somewhere.

Reviewer 2 Report
In this study, NARX Network with serial-paralllel structure is used to identify the unknown Aerial Delivery System with the Ram-Air Parachute. However, in my opinion, several concerns listed as follows should be clarified or revised.
- I think the model size/Flops/speed are also very important forSystem Identification of an Aerial Delivery System.
- The authors should highlight the limitations of the proposed method.
- The analysis regarding performance improvement of the proposed method is not so convincing.
- The design details of each proposed module are elaborated in section 3. Unfortunately, there is no corresponding theoretical analysis to support the rationality of the design.
- Related work is a bit inadequate. For example,HFNet, RLLNet, etc.

Reviewer 1 Report
Noise in the instruments cannot reflect the fact that wind decouple measurements and vehicle performance.
