中文摘要
      本文采用环路成形H∞控制方法对一非线性锅炉,汽轮机系统进行设计,为了能方便地在实际工程中实现复杂的控制器,本文提出用多变量PID控制器逼近所得控制器的方法.最终简化的控制器由位于主对角通道的三个PI控制器及位于次对角通道的一个PI控制器实现,仿真表明所得控制器具有较好的信号跟踪、抗干扰性能,并能在较大范围操作点工作,从而具有较佳鲁棒性
英文摘要
      A loop-shaping H∞, controller is designed for a nonlinear multivariable boiler-turbine system.ln order to imple-ment the complex H∞ controller,we propose a method to reduce it to a multivariable PID controUer.The final simplified con-troller is composed of three main-channel PI controllers plus one off-channel PI controller. Simulation shows that the designed controllers bave good tracking,disturbance rejection properties,and robustness against the variations of the operation paints due to the plant nonlinearity.
