摘要
线性时不变系统的时域分析比拼域分析困难,因为在给定输入的请况下,为求解系统的完全响应必须由给定的系统起始值来确定系统的初值。该值不仅与输入、起始值有关,还与系统结构有关,很多经典的方法很好地解决了这一问题;但迄今未应用到初值定理,扩展了初值定理得应用范围,使之能提供足够的初值来求解系统的完全响应。
Analysis of the Linear Time- Invariant Systems in time domain is often difficult than the in frequency domain. For the former, in order to find complete solution of the systems for given inputs, the initial values must be to determine from the start values of the systems. These vales not only depend on the structure of the systems but also the input signals. A few classical methods have been introduced to solve this problem and obtain good result. So far, the initial value theorem does not be applying in this domain, as which only supply one initial value of system, are therefore interested in extending the scope of the theorem which made it supply enough initial values to solve the complete solution of the systems.
