摘要
研究了含状态变量积分项的一类状态时滞、控制输入时滞的非线性系统的鲁棒稳定性问题。给出了新的坐标变换,构造了Lyapunov-Krasovskii函数,并设计了相应的控制器,控制器的增益系数可通过求解线性矩阵不等式得到。数值计算实例表明,相对于某些控制器,所给出的控制器可使具有较大状态时滞的不确定线性系统一致鲁棒稳定,显示了该控制器具有较广泛的适应性。
Robust control stabilization problem for a class of continuous nonlinear systems with time- delays in state vector and control input and with state integration was studied. A special state transform, Lyapunov-Krasovskii function, and controller design was proposed. The controller gain was obtained through linear matrix inequality. This controller can make the systems with large state and control input time-delay asymptotic stable. Numerical example demonstrates that this controller can also guarantee asymptotic stability for nonlinear systems with uncertainties and large state time- delay and suitability.
