Computation of optimal output feedback gains for linear multivariable systems
S.S. Choi, H. Sirisena · IEEE Transactions on Automatic Control · 1974
For linear systems with quadratic performance indices, it is shown that the optimal output feedback gains can be computed using gradient techniques. Unlike previous algorithms, this approach avoids the solution of nonlinear matrix equations while appearing to ensure convergence. Computational results for a fourth-order system are presented.
