摘要
提出一种驱动运算方法和较大功率驱动电路。MCU通过HCTL-2032获取当前电机的转速,PID根据目标速度对上一时刻和当前时刻的速度运算得出下一个时刻的速度,并且通过驱动电路来实现。驱动电路主要由半桥驱动、MOS桥、光耦隔离和过载保护电路组成。
A motor current speed by eale bridge drive, computing method and a high-power drive circuit were proposed. Via HCTL-2032 and MCU speed can be obtained; and in line with the target speed, the PID control can work out the ulating the last and current speed, and achieve it MOS bridge, Opto-isolation and overload protecting through the drive circuit composed by circuit. , the next half-
