对于不确定或者未知输入系统,常规鲁棒观测器设计对系统和干扰有较多限制条件.区间观测器对系统具有宽松的前提条件,且对干扰只要求有界,因而区间观测器更具有广泛性.针对离散和连续的广义未知输入系统,研究区间观测器的设计问题,通过对离散系统和连续系统进行不同的变换,将系统转化为易于求取区间观测器系数矩阵的形式;然后基于相同的参数求取方式,给出广义系统区间观测器的设计方法.仿真结果表明了所提出方法的有效性和正确性.
For uncertain or unknown input systems, the conventional robust observer design has more constraints on the system and interference. The interval observer has loose preconditions for the system and only requires boundedness for the disturbance, so the interval observer is more extensive For the discrete and continuous generalized unknown input systems, the design of interval observer is studied. By transforming the discrete system and the continuous system differently, the system is transformed into a form easy to obtain the coefficient matrix of the interval observer. Based on the same , The design method of the generalized system interval observer is given.The simulation results show the validity and correctness of the proposed method.
