摘　　要：为使燃气轮机快速平稳地跟踪负荷设定值,提出了基于反步法的燃气轮机功率控制器;对燃气轮机-发电机系统非线性模型进行简化及坐标转换,通过反步法设计Lyapunov函数和中间虚拟控制量,计算得到控制律,并采用Simulink软件仿真验证本文设计的燃气轮机功率控制器的可行性和有效性。结果表明:与传统PI控制器相比,采用反步法的燃气轮机功率控制器提高了燃气轮机跟踪负荷设定值的稳定性和快速性,该方法有效、可行。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.
