摘要
本文介绍了用于时滞系统的Smith预估补偿控制、采样PI控制和预测控制方法的原理,并对一阶纯滞后对象,采用Matlab工具对其控制性能进行仿真比较。仿真结果表明,Smith预估补偿算法在滞后被控对象模型已知的情况下能够取得较好的控制效果,而在模型参数未知或不准确情况下,适合采用采样PI控制或预测控制。
The Smith predictive compensation, the sampled-data PI and the predictive control are compared by using Matlab. The results show that Smith predictive control is suitable for systems whose models are known, and the sampled-data PI and the predictive control are suitable for systems whose models are not known exactly.
