音圈电机超调控制研究

Research on Overshoot Control of Voice Coil Motors

针对音圈电机作动器阶跃响应超调的问题,提出了一种简单有效的抑制控制技术。通过两次阶跃输入相互抑制规划,有效地抑制了作动器的超调问题,并分析了响应误差和两次阶跃输入信号间的关系。通过仿真和实验验证了驱动控制的有效性。

For the thrust overshoot of voice coil motors that appears in response to step inputs, a simple and effective control strategy is investigated based on the method of restraining mutually by re- sponse. The thrust overshoot is solved effectively by the inputs, in which the original step input is divided into two step inputs with different ampli- tudes. An analytical formula is derived to express the relationship between the two step inputs and the output error. The effectiveness of the proposed method is verified by simulation and experimental results.
