摘　　要：采用多容标准传递函数确定控制系统的期望极点,利用能控标准形和梅森公式导出控制系统的传递函数,提出了一种新的锅炉汽温状态反馈控制器的标准传递函数设计方法。该方法可同时完成动态和稳态设计,且只包括简单的代数运算,所用参数的物理意义明确,便于应用。通过仿真试验验证,表明该方法正确和有效。Adopting multi-capacity standard transfer function to determine the desired polar points of the control system,the transfer function of the control system has been derived by using the controllable standard form and the Mason＇s formula,putting forward a new design method of standard transfer function for the state feed-back controller of boiler steam temperature.The said new design method can simultanuously complete the dynamic design and static design,and only simple algebraic operation being included,the physical meaning of used parameters being clear,and being convinient in application.Through emulation test,it is verified that the said new method is correct and effective.
