中文摘要
      采用积分等式方法处理Lyapunov-Krasovskii泛函导数中的交叉项, 利用牛顿–莱布尼兹公式和自由权矩阵来保留状态的导数项, 标称系统的稳定性条件中的系统矩阵和Lyapunov矩阵得以分离, 再通过参数依赖Lyapunov-Krasovskii泛函得到多胞不确定型系统的鲁棒稳定性结论, 最后数值算例说明稳定性条件的有效性.
英文摘要
      The cross-product terms in the derivative of Lyapunov-Krasovskii functional are disposed by using the integral-equality approach, and the state-derivative term is reserved by employing Newton-Leibnitz formula and freeweighting matrix. System matrices and Lyapunov matrices in the stability condition of nominal system are separated; thus, robust stability criteria for polytopic-type uncertainties system are obtained easily. Finally, numerical example is given to demonstrate the effectiveness of the proposed method.
