Abstract

A kind of adaptable nonlinear controller is proposed and designed for a multi-input multi-output nonlinear boiler-turbine system. With the extended state observer to observe the influence of control loops, an approximate decoupling system is obtained and the desired dynamical equations are designed separately. The simulation results demonstrate that this control system has good tracking property with zero steady-state error and little influence between control loops. The controller can reject certain of input disturbances and have work well even if some parameters change.
