APPS:  Modern control theory questions
------------------------------------------------------------------------------------
Hello sir,

I want to design a controller based on LQR Design concept. How do I choose the weighting functions in that? Can we choose arbitrarily or there is any method for that? I have A,B Matrices. Based on the gains got from LQR design, I want to get STABLE system (closed loop Eigen values with Negative real part.)

Note: At present (before LQR design), I have Eigen values as UNSTABLE. (Some Eigen values real part in RHS plane.)

How to write the MATLAB coding for that?
