摘　　要：提出了一种锅炉汽温状态反馈控制系统的多容惯性标准传递函数的设计方法,从而解决了锅炉汽温状态反馈控制设计中的高阶、有零点过程、稳态设计和计算复杂的问题。采用Matlab中的Simulink平台,构建了通用状态反馈控制的仿真试验系统。仿真结果表明,状态反馈控制系统较PID控制系统具有无超调和调整时间短等优点,且过程模型数据、期望模型数据、状态观测矩阵和状态反馈矩阵的各元素值均无计算误差。A design method of a multiple capacity process transfer function standard form about the state feedback controller for a power station boiler steam temperature control system was put forward,thus to solve the problems occurred during the state feedback controller design,such as the high-order system,zero-placement,stable state design and complicated computation.The Simulink platform in Matlab was employed to build up the simulation test system for general state feedback control system.The simulation results show that,compared with the PID control system,the state feedback control system had no overshoot and the adjusting time was shorter.Furthermore,its process model data,expectation data,state observation matrix and state feedback matrix all had no calculation errors.
