摘　　要：研究电力系统的优化控制问题,针对提高系统的品质特性的要求,在两轴数控转台中采用传统的PID控制参数难以整定跟踪性能。将神经网络引入到转台控制PID参数的寻优过程中,设计了基于BP网络的PlD控制算法器,建立了转台控制系统的数学模型,将基于BP网络的PID算法的控制进行仿真。仿真结果表明所设计基于BP网络的PID算法器跟踪精度高、性能稳定、鲁棒性强,证明提高了控制系统的精度和跟踪性能。In this paper,the classic PID control parameters of two axis digital control turntable are difficult to tune,,neural network is thus introduced in the optimizing process of PID parameters turning.A mathematical model of control system of turntables has been set up,during which PID controller is designed based on BP network.In addition,the PID algorithm based on BP network is simulated.The results indicate that the PID controller based on BP network has higher tracking accuracy,stabler performance and stronger robustness,which provides a solution to the problem of inadequate precision required by classic PID control as regards to the control precision.
