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。
針對壓縮空氣儲能繫統的功率可控性，首先利用反饋線性化方法將儲氣室多輸入、多輸齣非線性模型線性化，再對繫統選擇閤適的極點，應用多變量極點配置方法對儲氣室氣體溫度和壓力進行控製。倣真結果錶明，該方法在控製器輸入耑施加階躍信號且增大儲氣室進氣閥開度後，能夠使得氣體溫度和壓力快速地迴到平衡狀態，且波動很小，具有很好的控製效果。

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.
