The Design of Electro-hydraulic Servo System Based on Neural Network PID

For the characteristics of electro-hydraulic servo system such as non-linear and time change, a new type of PID controller based on neural network is presented in this paper. The hardware uses TMS320LF2407 DSP chips as the main processor. The software uses neural network PID controlling algorithm. And focuses on the design of neural network PID control. The simulation for neural network PID control algorithm by using the Matlab shows that the controlling algorithm has significant effect in improving static and dynamic characteristics of the system.
