Frequency response is the analysis of the response of systemswhen subjected to a sinusoidal change in input. When a linear system is subjected to a sinusoidal input, its ultimate response is also a sustained sinusoidal wave, with the same frequency. The figure below compares the output response of a system (solid line) with a sinusoidal input (dashed line) disturbing the system

System compensation is the process of designing a controller that will produce an acceptable transient response while maintaining a desired steady-state accuracy .These two design objectives are conflicting in most systems ,since small errors imply high gains reduce system stability and may even drive the system unstable .Compensation may be thought of as the process of increasing the stability of a system without reducing its accuracy below minimum acceptable standards

(1)只对对定常线性系统有意义; (2)系统初始值(状态)为零; (3)既可对系统求取,也可对元件求取 (4)不同的系统传递函数可以相同

(1)极点完全决定系统的稳定性; (2)极点在很大程度上决定系统的动态性能;即:极点决定系统响应的类型;极点与零点一起决定系统响应的幅值;
