A state feedback design method for single input, time invariant discrete time linear systems is proposed. The proposed approach differs from competitive designs such as pole placement design and linear quadratic design in the sense that the obtained class of control laws contains only one user parameter. The parameter is intimately connected to the desired(More)
A design method that makes a trade-off between noise reduction and stability requirements is suggested in the case when the process is modelled as a time invariant linear stable plant. The suggested controller is obtained by modifying the well known LQG-controller. Only the SISO-case is treated here. We give analytical expressions on how stability margins(More)
