Abstract：A loop-shaping H∞ controller is designed for a nonlinear multivariable boiler-turbine system.In order to implement the complex H∞ controller,we propose a method to reduce it to a multivariable PID controller.The final simplified controller is composed of three main-channel PI controllers plus one off-channel PI controller.Simulation shows that the designed controllers have good tracking,disturbance rejection properties,and robustness against the variations of the operation points due to the plant nonlinearity.
