locking two signals in Simulink

[buraka]

i want to lock two signals that one is the sawtooth signal at 5V@50Hz, the other is main 50Hz in Simulink. How can i achieve it? That is very important and urgent for me .
Many thanks

Hi buraka !

Here is the model in Simulink (Matlab ver. 7.1) that you search.

Hi Albo,
Thanks your interest. i am sending my simulink file. The circuit wiil work as a temperature controller. i generate a sawtooh waveform using Signal generator. You can seeat top of mdl file. But this signal have to synchronize with main voltage 220V@50Hz. i can use a voltage transformer(220V/6V) to take sample from main because my dac card works max 10V. But how can i synchronize these signal? What is your opinion?
