【摘要】 推导了多变量广义预测控制算法,该算法能有效地处理过程的不稳定性和非最小相位特性,并具有良好的解耦性能。同时提出一种处理纯滞后对象的新方法,即将近似法和广义预测控制相结合解决时滞的方案。这种方法可以解决通道之间时滞不同的对象,并且针对广义预测控制算法的复杂性对其简化算法(多变量单值广义预测控制算法)进行了研究。通过仿真研究表明,多变量单值广义预测控制算法在跟踪性、鲁棒性、抗干扰能力等方面都得到很好的控制效果。更多还原

【Abstract】 Multivariable generalized predictive control(MGPC) algorithm was deduced in this paper.It can effectively handle the instability and the non-minimum phase of the process.Furthermore,it has good decoupling performance.A new method to handle the pure delay of a process by combining the approximation method with the generalized predictive control was proposed,and the different time delay could be handled.A reduced method was presented i.e.multivariable single generalized predictive control algorithm to simplify the complexity of MGPC.Simulation shows that this algorithm achieves a good result in tracing property,robustness,anti-interference etc.更多还原
