I can get Time-Response when I simulate any control system using Simulink, but I want to see Frequency Response such as (Bode plot or Nichols Chart, etc).
Dear Hazim
This will help you http://www.mathworks.com/help/slcontrol/ug/bodeplot.html?refresh=true
if you want to call another simulink file from inside simulink then search model referencing in MATLAB docs

Dear Hazim,
One may do it by selecting the following in Simulink environment, after creating a new model:
Tools -> Control Design -> Linear Analysis
A configuration window will pop. You may analyze the LTI representation of any system by choosing the INPUT and OUTPUT from the Simulink model from the configuration window. Then, any frequency response (as Bode and Nyquist plots as well) may be online achieved meanwhile you, e.g., tune you control loop.
Hope that helps you.

As Rafeal notes the answer is YES. You can get Bode, Nyquist and root locus, pole-zero and step response. If you use the Simulink PI controller then it also allows automatic tuning with manual over ride. Quite nifty. One may move poles etc to see effect on step and bode response for example. One may have all at same time if need be.
Simulink also has the Response Optimisation toolbox which will allow you to import external responses and then will automatically optimise the controller parameters to ensure response within the defined response boundaries.
As is normal junk in, junk out so you must have a handle on what may be realistically achieved.
Isome steps needs to applied to get the bode plot, please check this link.
