针对系统中普遍存在时滞和系统不确定性现象,基于分段二次李雅普诺夫函数稳定性理论,讨论一类受干扰的不确定离散时滞模糊双线性系统的广义H2稳定控制问题。通过设计非脆弱分段状态反馈控制器,使闭环系统在允许参数不确定范围内广义H2稳定,控制器的设计可以通过序列线性规划矩阵方法(SLPMM sequential linear programming matrix method)方法求解得到。仿真例子验证了该方法的有效性。
The paper presents generalized H2 control for discrete time-delay fuzzy bilinear systems with parameters uncertainties and disturbances. Based on piecewise quadratic Lyapunov function, the piecewise no-fragile state-feedback H2 controllers are designed by using of SLPMM, which ensure the generalized H2 stability of closed-loop system for all admissible uncertainties. Finally, simulation example shows that the approach is effective.
