Low-Computation Adaptive Saturated Self-Triggered Tracking Control of Uncertain Networked Systems
Round 1
Reviewer 1 Report
Authors are studied and presented well.
I have some questions; 1. How are the functions Φ1 and Φ2 chosen in the numerical examples, is there any condition to choose?. 2. Is it possible to extend this problem to three variables? like x1, x2 and x3. If so, try to present those results. 3. What is the computation time for proposed controls and pre existing controls. Further, instead of choosing some particular function (Numerical examples), if authors studied real life applications it will be good for readers.Author Response

Reviewer 2 Report
In the paper the problem of tracking control of uncertain network systems
against input saturation i considered. To solve the problem a low-computation adaptive self-triggering control method using prescribed performance is introduced. The suggested controller successfully circumvents the problem of complexity explosion found in the conventional
back stepping method and also saves communication resources without using any filters. The auxiliary design system effectively solves the input saturation problem as all of the closed-loop system signals remain bounded. The proposed method is confirmed with numerical simulations.

Reviewer 3 Report
The current paper investigates the problem of tracking control of uncertain network systems against input saturation, the problem is solved by introducing a low-computation adaptive self-triggering control method using prescribed performance. The proposed controller successfully circumvents the problem of complexity explosion found in the conventional backstepping method and saves communication resources without using any filters. The theory is validated using simulations.
