摘　　要：为了解决快速反射镜在传统比例-积分-微分(PID)控制下超调量大及稳定所需时间长的问题,引入自适应模糊算法优化控制器参数,提高控制性能。根据音圈电机快速反射镜的构成与工作原理,构建音圈电机快速反射镜的闭环控制模型,并针对模糊控制器中的隶属度函数及论域进行优化;通过现场可编程门阵列实现自适应模糊增量PID控制器,并进行了仿真及实物测试。结果表明,自适应模糊增量式PID控制器能使整体闭环过程“零超调”、“零振荡”,同时相比于传统PID控制器,系统稳定所需的时间缩短了17.5%,系统带宽提高了16.7%。该方法可有效提高快反镜的控制效果,可应用于其它需要高精度控制的系统当中。To solve the problem of large overshooting and long time needed for stabilization of fast steering mirror(FSM)under traditional proportion-integration-differentiation(PID)control,adaptive fuzzy algorithm was introduced to optimize the control and improve the control performance.Based on the structure and working principle of the voice coil actuator(VCA)fast steering mirror,a closed-loop control model was constructed.The membership function and domain in the controller were optimized,and the adaptive fuzzy incremental PID controller was implemented through field-programmable gate array(FPGA).Simulations and physical tests were conducted.The results show that the adaptive fuzzy incremental PID controller can achieve“zero overshoot”and“zero oscillation”in the overall closed-loop process.At the same time compared with the traditional PID controller,the time required for system stabilization has been shortened by 17.5%,and the system bandwidth has been increased by 16.7%.This method can effectively improve the control effect of the fast steering mirror and can be applied to other systems requiring high-precision control.
