针对一类不确定线性时滞系统,同时考虑其暂态性能和稳态性能,提出了混合稳定的概念和控制策略,使得闭环系统在满足输入约束条件下,在给定的时间区间内有; 限时间稳定,在无穷时间区间上渐近稳定.将混合稳定控制问题转化为线性矩阵不等式(LMI)约束非凸优化具有可行解问题.通过锥补线性化算法求解状态反馈; 控制器使得闭环系统混合稳定.最后,通过一个无人机仿真来验证控制器设计方法的有效性.For the purpose of aiming at a class of linear uncertain time-delay; systems,the concept of mixed stabilization and control strategy are; given under the consideration of the transient and steady; performance.The closed-loop system obtained yields the finitetime; stability within a given time interval, meanwhile it also yields an; asymptotic stability in the sense of Lyapunov.Then the control problem; can be transformed into a feasible problem of non-convex optimization; with linear matrix inequality constraints. Moreover, the cone; complementarity linearization algorithm is used to obtain a state; feedback controller. Finally, simulation results of an unmanned aerial; vehicle demonstrate the effectiveness of the method.
