Suggestions

Hi Dandan Wang,

I am glad to read your page about Control Theory which is very interesting and instructive. I have gained a general and initial understanding of control theory and also got to know how control theory can be applied to actual systems. However, from my perspective, there are still several aspects to be improved as follows:

1. There are some grammatical errors in the page which you should proofread and correct. For example, The control theory deals with how an intelligently perceive, reason, and behave in an environment. It seems that the word "agent" is missing in this sentence. Here is another sentence: Each components in this system is equally important for contributing to the global, complex behavior. Decentralization is useful in many ways, for example, it is applied in operations over long distance. The word components should be changed to component.

2. Section Controllers and control theory is not very clear to me. You present several mathematical formulas whithout explaining how they should be applied. You may need to elaborate the significance of these equations by specific examples and illustrations.

Sincerely,

Ke Dai
