　　Mr. Yi have ever took my course "Introduction to Control".I was deeply impressed with him not only the good score "A" he got inthe 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 theControl and System theories not mentioned in the autobiology of my class and todiscuss the development and application of control theory in Science andIndustry with me. He imagined this theory is truly an amazing subject. Ifpeople understand and use it very well, this world will get better."Well!" I thought, " This young man is really likeControl."

　　Then he took part in my research "Design of SinusoidalOscillators Using the Theory of Variable Structure Systems" (published inthe Int. J. of Electronics, 1992, Vol. 72, No. 1) to design the oscillatorcircuits. From simulating the circuits he designed with PSPICE to assemblingthe electronic elements. he shown me the enthusiam and hardily spirit in hiswork.When gettinga new idea or finding some questions,he always shared hisopinion about how to overcome the error or improve the experiment results to me.Aftertry-and-error and ameliorating the circuit many times, we finally got a refinedbut good-performance oscillator.

　　Mr. Yi also got admirable grades in a couple of courses of controland systems, I truly believe he has strong learning capability and enthusism inthis field. So I no doubt that he will become a good student in your esteemeddepartment. Should you need any further information about Mr. Yi, please donothesitate to contact me.
