| 摘 要： | 槽式太阳能集热场出口温度的控制因其受到干扰的影响并未很好解决.针对该问题,该文提出一种双模态模型预测抗干扰方法.包括:将槽式太阳能集热场中除可测干扰外的所有扰动当成集总干扰,然后提出一种改进的干扰观测器用来观测前述集总干扰,最后观测值作为前馈信号被补偿到基于双模态模型预测控制的反馈控制器中以消除扰动的影响,并给出闭环系...

| Abstract: | The control of outlet temperature of parabolic trough solar field(PTSF)is challenging due to the existence of disturbances.To this end,a dual-mode model predictive rejection control method is put forward,in which,all unmeasurable disturbances are regarded as lumped disturbances.An advanced disturbance observer is designed to estimate the lumped disturbances,and then the estimated value is used as feedforward compensation to the feedback controller based on dual-mode model predictive control.Stability analysis of the closed-loop system has been presented.Simulation results show that the proposed controller can achieve unbiased control of the outlet temperature of the PTSF with small overshoot and short settling time in the presence of complex disturbances. |
