穿越频率(crossover frequency),带宽(bandwidth)ωb还有自然频率(natural frequency)ωn是可以近似相等的。因此穿越频率的大小也会影响响应的速度。 2.开环Bode Plot曲线的形状 我们在之前提到过开环Bode Plot的低频与系统稳态误差对应相关,高频部分与噪音抑制对应相关。联系本篇中的Bode Gain-Phase关系,我们又对穿越频...

If you take the limit as s goes to zero you'll get the gain when frequency goes to zero. But that's exactly the problem - we haven't studied how to take the limit as S goes to zero--we only studied to solve bode plot through laplace plane... although I don't recall a q...
The frequency domain analysis of systems is an important topic in control theory. Powerful graphical tools exist in classic control, such as the Nyquist plot, Bode plots, and Nichols chart. These methods have been widely used to evaluate the frequency domain behavior of system. A literature ...
In summary, to obtain the Bode plot for the magnitude of a transfer function, the asymptotic plot for each pole and zero is first drawn. The slope of the high-frequency asymptote of the curve corresponding to a zero is +20 dB/decade, while that for a pole is -20 dB/decade. The...
