In this paper we investigate the exact solution, minimizing the I , norm of the regulated output for a fixed input in SISO discrete-time feedback control systems. This is achieved by allowing non-zero steady state value and parametrizing the output to have a rational transfer function with chosen poles on the stability boundary. Alongside these Z,-optimal solutions, we obtain solutions in 11 with the same order transfer functions and arbitrarily close I , norms.
