摘要
针对零阶保持器采样系统 ,提出了保证采样系统当采样周期T → 0得到的离散系统极限稳定的判别定理 ,结果取决于传递函数的相对阶数 ;进一步 ,由于采样周期不可任意选取 (不能太大 ,也不能太小 ) ,当根据某一具体要求选定某一适当的采样周期时 ,基于一种输入变换的形式 ,利用对控制输入的变换 ,按着提出的保证相应离散稳定的规则 ,确保离散系统达到稳定设计的方案 。
For sampled system by zero order holder, a sufficient condition for the limiting stability of the corresponding discrete system when T→0 is proposed It depends on the relative degree of the transfer function Further, because the sampling period can not be too large nor too small, when we choose an appropriate sampling period according to some rule, based on a new type of transformation of the controllable input, using the presented rule in this paper, we get a design for stable discrete system in the case of chosen sampling period The design is completed by solving a series of constants \;
