This is particularly helpful

8、 when verifying polar plots (Nyquist plots), Bode diagrams and root loci. In addition, it can build an intuitive sense(直觉) of the relations between time and frequency domain behavior. We also will use MATLAB to check the validity of simplifying approximations that are often made when carrying out pr

11、inimize the need for a student to have to do anything that smells like programming. Remember that we want you to come away with an understanding of feedback theory in some depth. The computer is to aid in achieving this understanding and should be used intelligently as an engineering tool. CHAPTER 1
