【摘要】 针对线性离散系统 ,研究了状态方程和测量方程均包含未知输入干扰的状态估计问题 ,提出了一种新的状态观测器 (全阶比例积分观测器 )的设计方法。给出了这种观测器的存在条件。仿真结果显示了全阶比例积分观测器的良好性能。更多还原

【Abstract】 A new design method of a new kind of observer——full order proportional integral observer is proposed for linear discrete system with unknown input disturbance appearing both in process and measurement equations.Existent conditions of the new observer are provided.An illustrative example is given to show the better performance of the observer.更多还原
