The Application of Feedforward PID Control Based on FPGA in Universal Testing Machine

The stress and displacement control of the universal testing machine in material testing is a complex process. In order to ensure the accuracy of the test control process, this paper uses the feedforward PID control algorithm to control the universal testing machine to achieve flexible and accurate control purposes. The hardware implementation of the feedforward PID control algorithm is implemented by FPGA, and an accurate and efficient control system is constructed. The actual test shows that the control system achieves good displacement and stress control effects on the universal testing machine, and the control performance is improved.
