Abstract

Aiming at the requirements of the high precision and fast response in electro-hydraulic position servo synchronic control system with double cylinders

proportional-integration-differential iterative learning control strategy was employed to design and implement the control system where two-closed-loop and two-level control were adopted to make the two electro-hydraulic position servo systems track each other and ensure the dynamic synchronization of the double cylinders. The position error between two cylinders into system output signal was fed back while the digital control signal was adjusted by proportional-differential algorithm. The experiments show that the system is endowed with high control accuracy

rapid tracking ability and the precision of synchronization control approaches to 0.2%.
