Active Disturbance Rejection Adaptive Control for Hydraulic Lifting Systems with Valve Dead-Zone
Round 1
Reviewer 1 Report
The authors studied the motion control problem of hydraulic lifting systems subject to parametric uncertainties, unmodeled disturbances, and valve dead-zone. Both mechanical dynamics and hydraulic actuator dynamics with valve dead-zone of the hydraulic lifting system are modeled in detail. They also did stability analysis of the system. The theoretical results are verified with simulation results.
Comments:
1. Why the authors choose these values of Physical parameters of the hydraulic lifting system (Table 1).
2. 2. Add physical interpretation for obtained results in possible.

Reviewer 2 Report
This is a well written paper with appropriate and well-described and validated novelties. Before the publication, one thing should be clarified -- that this reviewer missed to understand:
- The authors claim that "the stability of the closed-loop system is assured". While Lyapunov functions are clearly described in the paper, the process of validating the stability of the system is not. Please expand on this.
