Fast Chebyshev transform

模型是进行控制与稳定性分析的基础，可以服务于仿真、系统行为分析、系 统内在机理分析、控制、预测、监督与故障诊断等目的。因此，建立系统的模型 已成为许多科学研究与工程实施的首要问题。(Model is the basis for control and stability analysis, can serve simulation, system behavior analysis, the internal mechanism of the system analysis, control, forecasting, monitoring and troubleshooting purposes. Therefore, the establishment of the system model has been implemented for many scientific and engineering the most important issue.)
