时滞过程的多变量广义预测控制算法

Multivariable Generalized Predictive Control Method for Time Delay Process

文章提出了用广义预测控制算法解决多变量系统的时滞问题的一种新的方案。该方法将时间滞后因子自然纳入系统的控制机制,可完全无误差的实现对时滞系统的控制,克服了传统近似法解决时滞所带来的误差问题。这种广义预测控制算法能有效的控制开环不稳定非最小相位系统,并有良好的解耦性能,在跟踪性、鲁棒性和抗干扰性方面都得到了很好的控制效果。

A new method is put forward,which can handle the time delay of multivariable system using multivariable generalized predictive control(MGPC) algorithm. It adds time delay to the controlling system that can control the time delay system inerrably and overcome the shortcomings of the traditional approximation method. It also can effectively handle the instability and non- minimum phase of the process. Furthermore it has good decoupling performance. And it also achieves a good result in tracing property, robustness, anti-interference etc.
