How can the output voltage of a power converter be dynamically adjusted in no-opto isolated applications (using LT3748)?

I am using LT3748 in a flyback configuration to generate a regulated 2V-5V/3.5A output from 10-30V input voltage and would like to control the output voltage from a reference signal. I tried sourcing/sinking current to/from the reference point (Rref) but the output is not well regulated (the output voltage does not change linearly with the reference and there are regions where large 1-10Khz oscillations occur). Is there any other way to dynamically control the output voltage?
