【Abstract】 Based on Riccati inequality approach, the definition of guaranteed cost systems with disturbance attenuation H_∞performance is presented. The design approach to a state feedback controller for the guaranteed cost is proposed. The close-loop systems satisfy a given disturbance attenuation H_∞performance, provide a guaranteed cost and keep stability for all admissible uncertainties. Under some conditions the H_∞guaranteed cost controllers of the systems can be obtained via LMI. An example to demonstrates the freasibility and effectiveness of the results.更多还原
