The Design of Software Platform for Nonlinear System Analysis

Nonlinear system analysis is a particular chapter in "Automatic Control Theory". The Analysis methods are very complicated and difficult to be understood. According to the teaching needs of this part, a teaching software platform for nonlinear systems analysis is designed with MATLAB simulation tool. The nonlinear element and linear components against the typical structure can be easily modeled and the phase locus diagram and the curve which the description function analysis needs can also be gotten easily with this software platform. Basing on these curves, the system stability, dynamic property and steady-state errors can be analyzed. The design interface of the entire software is simple and the software can be used easily, which can greatly reduce the workload of the teacher and improve the quality of teaching.
