The paper presents a linear feedback approach to solve the stabilisation problem of linear discrete systems with additive-type bounded uncertainties. The approach is based on the linear quadratic (LQ) regulator theory and establishes that stable performance is guaranteed for the system but within a prescribed region of attraction. Both state-feedback and output-feedback schemes are developed to implement the proposed controller.
