中文摘要: 执行器饱和与多时滞经常出现在许多实际控制系统中,因此,对执行器饱和与多时滞共存的控制系统进行研究具有重要的理论和实际意义。针对现有结果的局限性和不足,本项目将提出时滞相关的执行器饱和处理技术,并改进拓展现有的多时滞相关联的稳定性及性能分析方法。利用这些技术,并结合二次或非二次Lyapunov-Krasovskii泛函方法,本项目拟对几类具有执行器饱和与多时滞共存的控制系统,也即,线性多时滞系统、线性时滞关联大系统、中立型混合时滞系统、及T-S模糊多时滞系统进行全面而深入的研究,提出具有较小保守性的局部镇定条件、L2(l2)增益控制设计条件、及抗饱和补偿器设计条件。对一些具有执行器饱和与多时滞共存的工程控制系统,本项目也将给出相应的控制设计及抗饱和补偿器设计。显然,对本项目的研究就会有效地改进并补充现有的研究结果。

英文摘要: Actuator saturation and multiple time delays often occur in many practical control systems, therefore, it is of important significance in theory and practice to investigate the control systems with the coexistence of actuator saturation and multiple time delays. Aiming at the limitations and deficiencies of the existing results, this program will propose the delay-dependent techniques in dealing with saturation, and improve and develop the existing multiple time-delay interconnected stability and performance analysis method. Using these techniques, and combining with the quadratic or non-quadratic Lyapunov-Krasovskii functional approach, this program will perform the comprehensive and deep investigations for the control systems with the coexistence of actuator saturation and multiple time delays, i.e., linear multiple time-delay systems、linear time-delay interconnected large-scale systems、neutral systems with mixed time-delay、and T-S fuzzy multiple time-delay systems, and propose the less conservative local stabilization condition, L2(l2) gain control design condition, and anti-windup compensator design condition. For some engineering control systems with the coexistence of actuator saturation and multiple time delays, this program will also present the corresponding control design and anti-windup compensator de
