压缩空气储能系统储气室多变量反馈线性化控制

摘要

针对压缩空气储能系统的功率可控性，首先利用反馈线性化方法将储气室多输入、多输出非线性模型线性化，再对系统选择合适的极点，应用多变量极点配置方法对储气室气体温度和压力进行控制。仿真结果表明，该方法在控制器输入端施加阶跃信号且增大储气室进气阀开度后，能够使得气体温度和压力快速地回到平衡状态，且波动很小，具有很好的控制效果。%In order to solve the controllability problem of power in compressed air energy storage system, the feedback linearization method was applied to linearize the multi-input multi-output nonlinear model of the gas storage room.Then,the suitable poles of the model were chosen to control the temperature and pressure of the storage room with the preparation method of multivariable pole.The simulation results show that,this method can make the temperature and pressure return to equilibrium state very quickly when applying the step signal and increasing the opening degree at the inlet end.The temperature and pres-sure curves show little fluctuation,indicating this method has great control effect.
