Bidirectional Used in Value Motor by Superimposing Dither with Independent

为了实现阀用动圈式直线电机双向驱动及驱动过程中的颤振要求,研发了一种运用脉宽调制信号驱动新型动圈式直线电机的比例放大器,提出将脉宽调制信号与颤振信号相互叠加的驱动方案,能够实现对动圈式直线电机的颤振调节。理论分析与仿真研究表明,所研发的比例放大器性能可靠,能满足动圈式直线电机驱动要求。

In order to solve the problem of bidirectional driving of the liner motor for valve moving and the dither during the process, researched and developed an amplifier that driving a new type of dynamic electromechanical transducer by using pulse width modulated signal, put forward a driving scheme that overlay dither signal on a pulse width modulated signal. The solution could solve the hysteresis phenomenon of motor during the movements, improved static and dynamic performance of proportional valve, reduced motion loss. Theoretical analysis and simulation results showed that the proportion amplifier device was reliable and could meet the electromechanical converter moving coil drive requirement.
