摘要
针对有限时域脉冲响应模型,给出了双值预测函数控制(DPFC)算法,推导出了闭环系统的特征方程和传递函数,定量分析了阶跃响应系数对闭环系统稳定性的影响.采用脉冲响应模型簇来描述被控过程的不确定性,推导出DPFC闭环系统的鲁棒稳定条件.
A new form of double-value predictive functional control （DPFC） algorthm based on a finite impulse response model is discussed,and the characteristic equation of the closed-loop system is derived. Furthermore, model uncertainty is described by using a rang of possible plant impulse responses, then the robust stability condition for the new DPFC algorithm is derived by using the Jury＇s dominant coefficient lemma.
