Based on the discrete state equation of the system, the bounded variable simplex method of linear programming ( LP) is first applied to find the control sequences which meet the control constrains, then the cutting plane method is used to deal with state constraints. 在离散数学模型的基础上,首先应用求解线性规划问题的有界变量单纯形方法求出满足控制约束的控制序列,然后再利用割平面方法处理状态约束,以求得满足约束条件的最优控制。
However, when the linear part of variables has some bounded constraints, the methods based on variable projection strategy will be invalid. 一旦问题中线性部分的变量带有某些有界约束,变量投影方法就失效了。因此,针对可分非线性最小二乘的特殊形式设计不分离变量的算法是十分必要的。
In this paper, Robustness of singular perturbation system in the presence of bounded disturbance is researched, a new adaptive law is proposed, finite upper bound of state error, parasitics variable and mismatch, parameter are given. 本文对具有有界扰动的奇异摄动系统进行了鲁棒性研究,采用新的自适应律,给出了状态偏差,寄生变量和参数向量的有限上界。
The uncertainties and disturbance are bounded by unknown bounds, which are not need to be considered in the proposed adaptive controller design. When certain matching conditions are satisfied, the system with disturbance may track asymptotically the known object by the variable structure way. 自适应控制器的设计不涉及不确定性界和扰动界,运用变结构方法,可使带扰系统实现渐近跟踪。
