Hi,
If we look at the basic transfer function of a linear system, calculate the magnitude and phase, we can get any real pole (either at LHP or at RHP) will decrease the amplitude by -20dB/dec in the bode plot, but the phase shift the one at LHP is -90, and at RHP is +90. From here, we can see to stabilize a system, a pole at RHP is good. But if we look at the time domain, pole at RHP will oscillate (of course t->infinite, and frequency ->0), and definitely it is not good for a stable system. Can anybody show me how to plot a bode plot with a RHP pole, and how to understand it physically? How to generate a RHP pole? Thank you.
