摘要：The closed-loop control system of actuator consisting of giant magnetostrictive rod is designed and established regarding SCM (single cell machine) and personal computer as the core. The software and hardware required are also debugged and accomplished. The transfer function model of giant magnetostrictive actuator is built according to its structure. The digital control system using digital PID controller decreases the error of stable state on micro-actuator system without degrading much of its relative stability. Thus this system can establish the foundation for further developing the high-precision giant magnetostrictive micro-displacement actuator and improving the dynamic performance of its control system.
