摘要
为提高气动位置伺服系统的控制精度,针对其离散模型,分别对时延数和噪声多项式进行研究.通过实验证明,采用噪声多项式C为一阶多项式,过程模型时延数为2的二阶的离散数学模型,可以准确地反映气动控制系统的模型结构和摩擦力及其他扰动因素的影响.
Aimed at discrete model for pneumatic position servo system, investigation of time-delay and noise polynomial was carried out for improving its control accuracy. It was proved that, adopting second- order discrete model with first-degree noisy polynomial C and time-delay of two, the effects of model structure and friction in pneumatic control system and the other disturbance factors could be demonstrated accurately.
