【Abstract】 Robust control of Delta operator uncertain system and its closed-pole with circular region con- straint are studied.Based on Lyapunov stability theory and LMI method,the state feedback for Delta operator uncertain system is designed.Sufficiency condition of state feedback control law is derived. The solution of LMI provides a parameterized representation of the control law.A numeric example is given to demonstrate the effectiveness of the method.更多还原
