摘要
本文首先建立具有共轭复极点的传递函数的液压伺服系统离散化状态空间方程:X(K+1)=A(T)X(K)+B(T)V(K),着重讨论了如何求解系统矩阵A(T)控制矩阵B(T)中各元素值。然后讨论如何确定实际系统的性能指标,如何考虑实际的约束条件,最后按最优化理论确定数字控制器的算法及状态观测器的设计与连接。
In this paper, first the equation of discrete-state space with complexconjugate in hydraulic servo system,X(k+1)=A(T)X(k)+B(T)V(k), has beenestablished. Following discussing detailly about values of elements both in thesystem matrix A(T) and the control matrix B(T), the way for determing, thecharacteristic parametes and how to consider constraint conditions have beenprovided. Finally, according to optimal theory we introduce the selectingmethod of designing the numerical control device and state-observer devices,and their connection.
