篇1：控制和系统专业信
控制和系统专业推荐信
Dear Sir or Madam:
The purpose of this letter is to recommend Mr. Yi, a worthy candidate for admission to your graduate program.
Mr. Yi have ever took my course “Introduction to Control”. I was deeply impressed with him not only the good score “A” he got in the class but also thehighly active and devout attitude he learn Control Theory. Sometimes, he came to my office to ask me some interesting questions about the Control and System theories not mentioned in the autobiology of my class and to discuss the development and application of control theory in Science and Industry with me. He imagined this theory is truly an amazing subject. If people understand and use it very well, this world will get better. “Well!” I thought, “ This young man is really like Control.”
Then he took part in my research “Design of Sinusoidal Oscillators Using the Theory of Variable Structure Systems” (published in the Int. J. of Electronics, 1992, Vol. 72, No. 1) to design the oscillator circuits. From simulating the circuits he designed with PSPICE to assembling the electronic elements. he shown me the enthusiam and hardily spirit in his work.When gettinga new idea or finding some questions,he always shared his opinion about how to overcome the error or improve the experiment results to me.After try-and-error and ameliorating the circuit many times, we finally got a refined but good-performance oscillator.
Mr. Yi also got admirable grades in a couple of courses of control and systems, I truly believe he has strong learning capability and enthusism in this field. So I no doubt that he will become a good student in your esteemed department. Should you need any further information about Mr. Yi, please do nothesitate to contact me.
Sincerely Yours

篇9：闭环控制（反馈控制）系统是什么？
闭环控制（反馈控制）系统是什么？
据被控量与给定值的偏差进行控制，最终达到消除或减少偏差，闭环控制的三大特点：信号按箭头方向传递是封闭的（闭环）、负反馈和按偏差控制。闭环控制的主要优点是控制精度高，抗干扰能力强；缺点是使用的元件多，线路复杂，系统的分析和设计都比较麻烦，
把取出的输出量回送到输入端，并与指令信号比较产生偏差的过程，称为反馈控制。指令信号与被控量相减为负反馈，相加则为正反馈。不做特别说明，一般指负反馈。反馈控制就是采用负反馈并利用偏差进行控制的过程，是自动控制系统中最基本得控制方式。反馈控制系统的优点是能缩小或消除偏差，无论偏差的根源何在，他们都可以工作，具有普遍的适应性。缺点是比较被动。
