Hi Shivaleela,
Arduino hardware does not support changing the frequency of PWM wave. The frequency of the PWM signal on most pins is approximately 490 Hz. On the Uno and similar boards, pins 5 and 6 have a frequency of approximately 980 Hz.
Regards,
Zenin

Thanks Zenin!
but is there a work around to get the other frequency by modifying timer precsaler using simulink ?

Dear Shivaleela
this topic was discussed several times.
Please see for example:

Hi,
Use this library to change the PWM frequency on arduino:
Request for supporting variable PWM frequnecy on arduino is under consideration.
