Determining the Ramp Slope
Mathematically, the slope of this compensating ramp must
be equal to one-half (50%) the downslope of the output
inductor as seen from the control side of the circuit. This is
proven in detail in “Modelling, Analysis and Compensating
of the Current Mode Controller,” (Unitrode publication U-97
and its references). Empirically, slightly higher values of
slope compensation (75%) can be used where the AC
component is small in comparison to the DC pedestal, typical
of a continuous converter

原来是Unitrode的Application Note，早就有了，楼主最好发贴的时候有一个简要说明！

english paper about slope compensation is better that in chinese .
slop compensation is very important in peak current mode pwm controler.
especially in ccm .
