摘　　要：在航空装备大型离心机试验系统的研制中,为实现3×10~5kg·m^2转动惯量负载下平均10 g/s过载变化率的小超调量控制,采用过载-转速-转矩三闭环控制、转矩前馈控制、变参数PID调节相组合的控制方式,设计了高精度的速度随动控制系统,并在系统调试过程中,进一步优化了P、I参数,实现了大惯量、高动态控制指标要求。During the development of large scale centrifuge testing system for aviation equipment, in order to realize the small overshoot control with an average change rate at 10 g/s under the rotary inertia of 3 × 10^5 kg·m^2, a high-precision velocity servo system is designed by combining control modes of acceleration-rotating velocity-torque closed-loop control, torque forward-feedback control and variable parameter PID adjustment, and the parameters of P and I are further optimized in the process of system debugging. Finally, the requirements of large inertia and high dynamic control index are achieved.
