This paper studies the fault tolerant control, adaptive approach, for linear time-invariant two-time-scale and three-time-scale singularly perturbed systems in presence of actuator faults and external disturbances. First, the full order system will be controlled using v-dependent control law. The corresponding Lyapunov equation is ill-conditioned due to the presence of slow and fast phenomena. Secondly, a time-scale decomposition of the Lyapunov equation is carried out using singular perturbation method to avoid the numerical stiffness. A composite control law based on local controllers of the slow and fast subsystems is also used to make the control law ε-independent. The designed fault tolerant control guarantees the robust stability of the global closed-loop singularly perturbed system despite loss of effectiveness of actuators. The stability is proved based on the Lyapunov stability theory in the case where the singular perturbation parameter is sufficiently small. A numerical example is provided to illustrate the proposed method.

稀有金属矿物组成复杂,且矿物成分多样化,现有质谱方法对铍的测定以地质样品中或矿石样品中的低含量铍分析为主,也很少应用于分析铍矿石中伴生的难溶锡元素。本文以新疆大红柳滩高品位铍矿石并伴生较高含量锡元素的样品为研究对象,建立了铍矿石中难溶元素铍和锡同时测定的方法。利用高温熔融态过氧化钠强的复分解能力,将矿物中的坚固晶格破坏,使目标物转换为易溶盐被提取,通过10倍稀释降低样品基体盐分含量,保证长期测量的稳定性RSD低于5%,并对校准曲线进行基体匹配,以电感耦合等离子体质谱(ICP-MS)测定,铍和锡在5~2000ng/mL浓度范围内线性关系良好,相关系数均大于0.999,检出限为铍0.20μg/g、锡0.17μg/g;测量精密度高(RSD≤5%),测量上限为氧化铍5.6%,锡2%。本文方法线性范围宽,适合各种高品位铍矿石中铍和锡的分析。将建立的方法应用于分析新疆大红柳滩高品位铍矿等多金属稀有金属矿,氧化铍含量达到0.85%、锡含量达到0.078%的样品测量精密度良好;还适用于分析铍矿石中其他稀有元素锂铷铯铌钽和稀土元素。
