How to analysis the stability in the current-mode DC-DC?

Hi guys:
Now I need to design a DC-DC converter,switching frequency is 1Mhz,and I have read AI.Pressman's <Switching power supply design> ,and it seems to me that the book focus on the voltage-mode doing a lot of analysis on the voltage mode stability.But what about the current-mode,since the inductor will not contribute a pole to the loop,how to consider the current amp's gain,how to consider the slope compensation versus stability,and since the output pole now is inverse proportional to the loading resistor, so the output pole will vary greatly when loading is changing,this can be a problem to stability?
I couldn't find any books on these issues ,can you help me?And if u are confused as the same as me,maybe we can exchanged ideas and this may help,u can contact with me through the E-mail below.
Best Regards

Usually chose the compensation coefficient >1/2 and <1. That is, 1/2<Ma/Ml<1. Ma is slope of artificial ramp and M1 is slope of inductor current.
If Ma/Ml is too big, it comes close to be voltage mode. If Ma/Ml is too small, it will lead to sub-harmonic oscillation.

you can refer to Ridley'paper about small signal model for current-mode dc-dc
