遙遙無期的畢業.....

今天收到的,拖了將近半年,明明是投brief....應該三個月就會出來的,能說什麼呢,第二篇因為第一篇而被reject,而第一篇也因為些格式被拒.....怎嚜寫就是抓不到要領.....天....

Reviewer one:

The authors present a scalable method for reducing the number of H-bridge switches required for controlling a large number of bi-directional actuators. This is accomplished by arranging the actuators in a 1-dimensional array and having adjacent actuators share switches. Thus instead of 4n switches for n actuators, only 2n+2 switches are needed. The authors derive an optimal method for controlling the shared switches to achieve desired output. They present a design example and simulations to demonstrate the utility of their method when applied to audio amps.

I think this is a very clever idea and the paper does a good job of conveying important concepts in the 5 page limit. The proofs of their control theory relies on previous publications, which I don't have time to read, but appear to be technically sound. I approve their use of a design example to demonstrate the theory. The final results give conclusive evidence that their method works for a basic 2 actuator system. It will be interesting to see how the performance scales with number of actuators, and the authors identify this as primary future work in their conclusions.

 

Reviewer two:

In this reviewers opinion, the supposed contributions of the paper are too heterogeneous (a switch-efficient topology, a MIMO control method, and alternative sigmal-delta modulation) which results in an overall wide but shallow contribution which is not solid for publication.

- The topology for multi-load driving might be functional theoretically, but the challenge of guaranteeing that there is not instantaneous conduction shothrough, which would require very sophisticated deadtime policies, is not addressed.
- The discussion in section III including equations (2)-(5) is standard in the control theory discipline, and hence there is no clear added-value including it in the paper.
- The discourse in section IV and V is more suited to a control theory journal.

 

Reviewer three:

The numbers of switches required by the proposed topology make it suitable for controlling a small number of actuators, however, since the number of switches is of the same order than the number of actuators,  the proposal does not scale well when the number of actuators increase.

N parameter is used with different meanings. In the introduction N^2 is the number of actuators, but in section II, subsection A the number of actuators is N. This confuses the reader.

第三位先生說的甚至是不對的.... = =

好吧,再接再厲....這學期又要過完了哩.....
