<p>PROBLEM TO BE SOLVED: To enable system identification even in a digital input/output from/to a system represented by a differential equation including a high-order differential operator.SOLUTION: An information processing method includes processing for (A) generating a fitting curve represented by the linear sum of exponential functions about each of a digital input and a digital output stored in a data storage part for storing digital inputs of a physical system and digital outputs of the physical system represented by an equation including an m-th (m is an integer of one or more) differential operator, and (B) calculating a coefficient of a differential operator included in a first coefficient such that the first coefficient of each exponential function included in an expression obtained by the product of a differential operator and a fitting curve about a digital input coincides with a second coefficient of the same exponential function including in a fitting curve about a digital output.</p> |
