Reviewer 2 Report

Comments and Suggestions for Authors

In this paper, Sensorless HSPMSM control of an improved SMC and EKF based on immune PSO has been adopted. Overall, the paper is good however, some of the recommended corrections are listed as follows:

1.       The abstract mentions improvements in the convergence law and the use of a continuous function. It would be helpful to elaborate on the specific ways these improvements were made and how they contribute to the performance of the controller.

2.       The superiority of the newly developed ISMC over a traditional PI controller has been evaluated. What quantitative data or performance metrics were used to determine this superiority, and can the authors provide more insight into the comparative analysis?

3.       While discusses simulation results, it's crucial to question the robustness of the proposed controller in real-world scenarios. How does it perform in the presence of disturbances, non-linearities, and practical limitations that real systems often encounter?

4.       The asymptotic stability of the designed sliding mode variable structure controller has been mentioned. It would be valuable to inquire about the details of the stability analysis, the choice of Lyapunov function, and the conditions under which this stability is guaranteed.

5.       The method adopted is an extended Kalman filter (EKF) with immune particle swarm optimization (PSO) for rotor position and speed control. What is the novelty in this approach, and how does it compare to other sensorless control methods for PMSMs?

6.       Except simulation results, whether there are plans for experimental validation of the proposed control strategies in a real motor system.

7.       The method is intended for high-speed permanent magnet synchronous motors in flywheels. Could the authors discuss the potential broader applications of their findings and whether the developed control strategies can be adapted for use in other motor systems?
