非线性系统线性化后，线性系统的鲁棒控制方法就可用于控制器的设计[1 - 3] 。80年代以来，鲁棒控制理论得到了迅速发展，H∞方法和μ方法成为鲁棒控制设计的有效工具，并广泛应用于线性系统控制中 [4- 8] 。

Linear Fractional Transformation is adopted to translate the control of perturbation to the control of disturbance, then cost index is augmented, and with the min-max method, a robust receding horizon control law is derived. The sufficient conditions for the existence of the control law and closed-loop stability are also presented. The result is extended to time-invariant system with an infinite horizon, and its consistence with the robust control based on the concept of Quadratic Stability is verified.
