(2) ラプラス変換・伝達関数 260302

The transfer functions used in classical control theory are based on the Laplace transform. We will explain what the Laplace transform is, provide an image of it, and explain the mathematical formula it is expressed in. The definition of the Laplace transform can be understood by following the path "Fourier series expressed as a trigonometric function → Fourier series expressed as an exponential function → Fourier transform → Laplace transform." We will also explain why the Laplace transform is essential to control engineering.
