Matlab state space for feedback

Hi every one i need a help on urgent basis please help me And NOTE THAT for H(s)=(a*Tau*s+1)/(s

*Tau+1) H(s) is not unity i have to implement lqr,,,how can i get a complete augmented state space model upon which i can apply lqr.. (i know all the theory and command regarding lqr and block diagram reduction ,,,,,series,paralell,) The main thing is .......if H(s) has some dynamics upon changing its parameters there should be change in output response or not ,,??

I recommend you first understand what state space is and try to create the state space model yourself. Otherwise if you already have the transfer functions you can use the tf2ss() function to convert the transfer function to state space. I am not sure why you are confused if you know all the functions (series, feedback etc.).

Thanks Aquatris for your suggestion actually i am confused that H is the sensor transfer function how can we put its state space model into plant G model to design the lqr? becuase when i want to observe the output by changing the dynamics of sensor transfer function nothing has beed changed,,,,>> hope you get what i want to ask ???? please provide me some example for this case thanks once again
