I am using R14A and I have modelled angle tracking observer algoirthm in simulink. I have simulated model wih floating point and it works well. I used fixed point advisor. Although there are no errors, but the output is zero. Can anybody help us withthis.

The problem of getting all the output as zeros could potentially be related to the proposed data type settings which results in overflows. You could verfiy that in the histograms produced after simulation.
Try increasing the word length in the Settings section of the fixed point tool, allowing more room for calculation and hence avoiding overflows.
Thanks

Float subsystem also gives zeros as an output. You mean to say that after converting to fixed point both subsystems are giving zeros? Then please share the un-converted model.
