Abstract: The introduces the application of a limited angle torque motor in a servo value and presents a comprehensive design strategy for the controller of the limited angle torque motor. The proposal encompasses a closed-loop control strategy based on FPGA,which includes the implementation of three closed loops for position,velocity,and current control. Furthermore,it delves into the digital PID control algorithm and details the software and hardware design of the controller. The control strategy was subjected to simulation analysis through the utilization of MATLAB, and experimental validation was conducted using a prototype. The results indicate that the controller ' s performance aligns with the simulation analysis results,demonstrating advantages such as fast response and no overshoot. It meets the design objectives and fulfills the task requirements.
