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.
