摘　　要：考虑量测噪声对给料混合系统的影响,研究了给料混合系统的广义预测控制问题。针对给料混合单元状态空间模型,利用线性Kalman滤波器估计系统状态,并基于多变量广义预测控制理论设计广义预测控制律。仿真结果表明:控制器能够减少量测噪声对系统的影响,有效控制转轴转速,使出口质量流量达到恒定。The generalized predictive control problem of the feeding mixing system is studied by considering the effect of measurement noise on the feeding blending system.The linear Kalman filter was used to estimate the system state for the state space model of the feeding blending unit,and the generalized predictive control law was designed based on the multivariate generalized predictive control theory.The simulation results show that the controller can reduce the influence of measurement noise on the system,effectively control the rotational speed of the rotating shaft,and make the outlet mass flow rate reach constant.
