Abstract

A simple technique is introduced to synthesize an optimal controller, to achieve the following purposes in LQG optimal systems: (i) input-ouput decoupling; (ii) complete and arbitrary pole placement; (iii) some zero assignments in Re(s) greater than equivalent to 0, which may be convenient in dealing with rejection and tracking problems. Wiener-Hopf's technique (frequency domain approach) is employed, and two frequency-dependent weighting matrices are shaped to synthesize an LQG optimal controller, to achieve the aforementioned design purposes.
