基于MSP430和神经网络PID的直流双闭环控制系统

Double Closed System of Velocity Modulation of Direct Current Motor Based on MSP430 and NN-PID

双闭环直流调速系统,常存在一些非线性因素,使常规PID控制响应效果变差。介绍了基于MSP430F449单片机的双闭环直流调速系统,并在转速环引入神经网络PID控制器,实践证明系统响应更快更精确。

Due to some nonlinear factors in DC speed control systemes,this paper introduces double systemes based on MSP430F449 and NN-PID.NN-PID is used in speed control.And the system has a better symatic and steady state.
