基于RLADRC的燃气-蒸汽联合循环机组负荷控制研究

Research on Load Control of Gas-steam Combined Cycle Unit Based on RLADRC

为了进一步提高燃气-蒸汽联合循环机组控制中的负荷设定值跟踪能力和抗干扰性能,在线性自抗扰控制的基础上,提出一种引入动态干扰解耦的降阶线性自抗扰控制策略。该控制策略可以有效地提高控制器的跟踪能力以及抗扰能力。仿真结果表明,该方法相较于PID以及线性自抗扰控制,在负荷控制中的设定值跟踪能力和抗干扰性能表现更好。同时该方法对多变量负荷控制中各变量间的耦合影响也有很好的抑制作用。

In order to further improve the load setting tracking ability and anti-interference performance in the control of gas-steam combined cycle units,a reduced order linear active disturbance rejection control strategy with dynamic disturbance decoupling was proposed based on linear active disturbance rejection control.The control strategy can effectively improve the tracking ability and anti-disturbance ability of the controller.The simulation results show that compared with PID and linear active disturbance rejection control,the proposed method has better set value tracking ability and anti-interference performance in load control.At the same time,this method also has a good inhibition effect on the coupling effect between variables in the multivariable load control.
