Aiming at the project requirements for the electro hydraulic proportional control test bench and combined with relevant scientific research experiments (control strategy generation and verification),the electro hydraulic proportional control system based on CompactRIO was designed. The LabVIEW virtual instrument was use to construct control loop and design control strategy of PID and fuzzy adaptive PID.The system can be carried on simulation research, and also has a good humancomputer interaction interface,which is convenient for users.The results show that control purpose is realized successfully.
