If I understand it correctly, the output voltage is a function of the resistor R_Adjust and the voltage it is connected to, V_Radjust. It seems that chosing the resistor for maximum output voltage (0 Ohms) and then increasing the voltage decreases the output voltage, so it might be possible to use a well-filtered PWM output to generate a voltage for adjustment. For an adjustment range between 150V and 200V, it seems that the necessary voltage is between 0V (for 200V output) and 1.27V (for 150V output), so well within the limits of what can be generated from a PWM output. Depending on the input current of the adjust pin, an opamp buffer might be necessary as well.
