摘要
分析了广义预测控制的状态空间结构 ,指出其实质是状态反馈 ;推导了存在建模误差时闭环系统传递函数与标称系统传递函数之间的关系 ,并结合小增益定理给出了频率域中闭环系统鲁棒稳定的条件 ,仿真例子验证了条件的正确性 .
The state space structure of the Generalized Predictive Control(GPC) is analyzed. It is shown that GPC is a state feedback in nature. The relations between transfer function of nominal system and of closed loop system are derived in the presence of modeling errors, and the conditions for the closed loop system's robust stability in the frequency domain are given based on the small gain theorem. Simulation results demonstrate the effectiveness of the conditions.
