TMS320F28069M: I have computed a continuous control signal in 28069, but the output signal is pwm. How can I output my continuous control signal?

Hello, 

I have connect typhoon and 28069. Typhoon works as a microgrid, and 28069 works as a controller. I can compute continuous control signal in CCS, but the output signal of 28069 is PWM. 

I expect the card can output a continuous signal, such as -10 -----100. So, how can I do this? Many thanks.
