摘要
针对含不确定因素的多输入多输出微分代数系统,提出一种多指标非线性鲁棒自适应控制方法(multi-index nonlinear robust adaptive control,MINRAC),并将其应用于汽门开度与发电机励磁的协调控制上。数字仿真表明:在系统参数不确定和存在外部扰动的情况下,该方法能够使得系统的多个指标都运行在期望的工作点上而不发生静态偏移。对于不同类型的扰动,如有功功率阶跃,三相短路,该控制方法都能很好地镇定系统,并且能够消除机端电压偏差。与多指标非线性控制(multi-index nonlinear control,MINC)和多指标非线性鲁棒控制(multi-index nonlinear robust control,MINRC)相比,该文提出的方法能更好地兼顾系统的动静态性能。
The MINRAC(multi-index nonlinear robust adaptive control) was proposed for uncertain differential algebraic system, and applied to the steam-valving control and coordinated excitation control of synchronous generator. The digital simulation results show that the proposed method can make multi-index of the system run at the expected working point without static offset under the condition of uncertain system parameters and external interference. For different types of disturbances such as active power step and three-phase short circuit, the proposed approach can also stabilize the system well and eliminate the voltage deviation at the generator terminal. Compared with multi-index nonlinear control(MINC)and multi-index nonlinear robust adaptive control approach(MINRC), the proposed method can give better consideration to the dynamic and static performance of the system.
