【摘要】 传统电压控制模式的电机驱动电路系统频率都受电机的本征频率制约,其相位延迟会随负载的变化而变化。为了实现更高的系统频率,文章提出了一种电流反馈控制模式驱动电路。理论分析和仿真结果表明,这种控制模式的电机驱动电路解决了系统频率受电机负载本征频率制约的问题,相位的延迟也不随负载变化而变化。更多还原

【Abstract】 The system bandwidth of conventional voltage-control-mode motor driver circuits is limited by the intrinsic frequency of the load, and its phase lag is also load-dependent. To achieve higher system frequency, a current-feedback-control mode driver circuit is proposed. Theoretical analysis and simulation show a system bandwidth broader than the intrinsic frequency of the load and a load-independent phase lag can be achieved by using the motor driver based on the proposed control mode.更多还原
