本文建立了单机无穷大系统的小信号数学模型,将PID和线性多变量控制器的优点结合起来,利用模糊控制器进行协调控制,以增强系统的抗干扰性,增加系统的鲁棒稳定性。仿真结果表明所设计的控制器具有良好的控制效果。
In this paper, a small signal mathematical model of single-machine infinite system is established. Combining the advantages of PID and linear multivariable controller, the fuzzy controller is used for coordinated control to enhance the anti-interference of the system and increase the robust stability of the system. The simulation results show that the designed controller has a good control effect.
