A Design Method of the Boiler Steam Temperature State Feedback Controller

提出了锅炉汽温状态反馈控制器的一种新设计方法.该方法利用阿克曼算法计算状态反馈控制增益向量,并增加了稳态设计步骤.同时导出状态反馈控制的稳态增益设计公式.应用该方法可在完成动态设计后也完成了稳态设计,从而实现阶跃响应零稳态误差.已完成的仿真试验证明了所提方法的正确性和有效性.

A new design method of the state feedback controller for power station boiler steam temperature control system is put forward. The desired poles are placed with a multiple capacity process transfer function standard form. The control system transfer function is derived by the Mason＇ s signal-flow gain formula and the controllable norm model. The use of new design method can make it possible to finish the stable condition design and the transition process design at the same time. The new method is suitable for engineering application with the simple algebra computation and the significant parameters. The successful simulation test shows that the new method is effective.
