Abstract

To improve the capability of gas turbine unit in fast and stable tracing of load demands

the backstepping method based gas turbine control algorithm was put forward.The Lyapunov functions and virtual controls were obtained by backstepping after simplification and coordinate transformation of the gas turbine-generator non-linear model were finished.Then

the control laws were calculated

and the feasibility of the control algorithm was validated by simulation using Simulink.The results show that

compared with the conventional PI controller

the gas turbine controller applying the backstepping method enhances the stability and response time of the unit to the load demands.
