摘要
为提高燃-燃联合动力系统的动态性能,本文对系统运行模式切换过程的并车控制方法进行了研究。依据动力学与热力学原理,采用多平台集成仿真的方法建立了由三轴燃气轮机、螺旋桨和传动装置组成的燃-燃联合动力系统的集成仿真模型。在此基础上,将线性自抗扰控制与平行功率反馈策略相结合,提出了PD-ADRC串级控制方法,建立了并车控制器模型,对燃-燃联合动力系统的并车和解列过程进行了仿真研究。结果表明:PD-ADRC串级控制可以有效控制燃-燃联合动力系统的并车、解列过程,负荷转移时不会出现功率超调与振荡现象,与传统PID控制相比,可以有效提高燃-燃联合动力系统的动态性能。
The control method for the merging operation in working mode switching is studied to improve the dynamic performance of combined gas turbine and gas turbine(COGAG)systems.An integrated simulation model of a COGAG system consisting of a three-shaft gas turbine,propeller,and transmission device is established on the basis of dynamics and thermodynamics principles by using a multiplatform integrated method.On this basis,the linear active disturbance rejection control(ADRC)and parallel power feedback strategy are combined for simulation.Then,a PD-ADRC cascade control method is proposed.Furthermore,a controller model is established to perform simulation tests of the paralleling and disconnecting operations of the COGAG system.The simulation results show that the COGAG system can be controlled effectively by the PD-ADRC method and that power overshoot and oscillation do not exist in dynamic processes.Compared with the traditional PID control,the controller designed in this work can improve the dynamic performance of the COGAG system.
