Library for Analysis and Synthesis of Control Systems Using the Graphing Calculator

The graphing calculator, Voyage200, is a calculator which has the Derive system as a computational engine and can do symbolic manipulation. It has a large liquid crystal display (128 × 240 pixels) as for a calculator and various responses can be drawn on it. Furthermore, it can be easy to make user-defined functions on it and extend to solve specified problems. Taking notice of the high potential and its portability, we develop the library for analysis and synthesis of linear control systems. In this paper, we introduce typical programs including our library which consists of programs more than 100 and examine the effectiveness at the stand point of control education. According to the results of several examples, our system may be available for the 4th order systems or less, as regards computational time. However, it must be enough as education of the beginners of control engineering and powerful handheld tool.
