直流调速系统电源扰动情况下的最佳调节

Optimal Adjustment for DC Speed Regulation System under Power Disturbance

在直流双闭环调速系统中,电流内环主要抗电源扰动。针对电流内环从数学模型到动态响应的过渡过程,进行定量分析,说明三阶对称最佳比二阶工程最佳更具有良好的抗干扰性能指标。

The inner-loop current mainly resists the power disturbance in the DC double-closed loop speed regulation system.This paper provides the quantitative analysis of the process from the maths model to the dynamical response of the inner-loop current.Based on the optimal adjusting principle,it shows that third-order symmetric optimum system reveals better ability of disturbance resistance than second-order engineering optimum system.
