Multi-Mode Extension Control of Pump-Control Electro-Hydraulic Servo System Based on PLC
To satisfy the requirements of rapidity, stability and accuracy in positioning of pump-control electro-hydraulic servo system, the paper designs a multi-mode extension control switcher, which can realize switchover between different control modes and give full play to each control mode to meet the requirements of control system for various performances. In order to apply this method to practice, the principle, the control algorithm process and part program segments of multi-mode extension control realized by Mitsubishi PLC was introduced, and experiments was done to verify the control effect. The result shows that multi-mode extension control of pump-control electro-hydraulic servo system using PLC can satisfy the demands of control system.
