Is it essential to specify bounds in process model estimation using system identification toolbox? I'm not getting the expected process model from estimation.

Not necessarily. You only need bounds if you think your model is overfitting the data (e.g. due to not enough data points and/or imperfect system excitation) and you know some solutions are wrong due to prior knowledge about the true system.
But before starting to add bounds, make sure you have done everything else correct! Including:
