Round 1

Reviewer 1 Report

  • In Abstract, what is “preview fixed preview time”?
  • In Introduction, the full names of BP, MPC and PID must be given. The principle of the sliding-mode control must be briefly introduced and the recent progress of the application of sliding-mode controllers to vehicle control must be reviewed. The main contribution of this paper must be summarized.
  • The control objectives must be formulated.
  • In Section 4.1, the Lyapunov function must be given.
  • In Section 5, please use a table to summarize the parameters of the vehicle used in simulation tests.
  • In Section 5, please use a table to summarize the parameters of sliding-mode controller used in simulation tests.
  • The sampling period used in the simulation tests must be given.
  • The authors should compare the performance of the sliding-mode controller with one existing controller in simulation tests to demonstrate the superiority of the former.

Round 2

Reviewer 1 Report

The manuscript has been improved. Only one issue need to be dealt with:

In line 49, the full name of MPC is "Model Predictive Control". 

Author Response

Thank you very much for your valuable advice. I am sorry for this small mistake. It should be “Modern control algorithm MPC (Model Predictive Control)”.

Reviewer 2 Report

The authors diligently tried improving the paper. However, some issues are to be corrected:

  1. The use of the low pass filter in (31) in order to mitigate the control (28) high frequency switching is not appropriate, since it adds unmodeled dynamics that can yield lower frequency limit cycles.
  2. Overall SMC design is still immature. I would recommend citing and reviewing classical books on SMC. 
  3. Text in the rows 161-164 is to be written in a passive voice.
