本文分析了在设计多输入多输出高温加热控制器中利用降阶模型方法的可行性。我们在校准焦点的超声波系统下的生物转移均等模型定差分膨胀的基础上制作了状态空间热模型,并利用平衡实现简化这些状态空间热模型,将降阶准则列成表格。结果表明,通过平衡实现,模型规模可 This paper analyzes the feasibility of using the reduced-order model in designing a multiple-input, multiple-output, high-temperature heating controller. We make a state space thermal model based on the differential expansion of the equalization model of biological transfer under the ultrasound system with the calibration focus, and use the balance to simplify these state space thermal models. The results show that the scale can be achieved through the balance
