| Outline of Final Research Achievements |
Usually, symbolic computations in a computer algebra system do not permit any numerical errors, and floating point arithmetic and power series computations are not allowed. Therefore, so far, applications of symbolic computations for controller designs has been limited.
In this study, we apply symbolic computations to controller designs, utilizing power series computations. We approximate a mathematical expression with its power series expression. It is possible to perform arithmetic operations such as additions, subtractions, multiplications and divisions on power series, which enable us flexible symbolic computations.
