The invention discloses a general
miniaturization digital electric steering engine controller and a control method thereof. The general
miniaturization digital electric steering engine comprises a
signal conditioning module, an AD sampling module, a parallel-to-
serial module, a steering engine
algorithm module, a serial-to-parallel module, a steering engine driving control module, a steering engine driving module, a displacement detecting circuit and a current detecting circuit, wherein the displacement detecting circuit and the current detecting circuit output analog position signals and analog current signals of m steering engines, and m is greater than or equal to 2; one channel of serial position
signal, one channel of serial current
signal and one channel of serial instruction signal are obtained by the
signal conditioning module, the AD sampling module and the parallel-to-
serial module and are fed into the steering engine
algorithm module; the steering engine
algorithm module is used for performing position and current double
closed loop control on a steering engine
drift angle and outputting one channel of serial
control signal; and the serial
control signal is converted into m channels of parallel control signals required by the steering engine through the serial-to-parallel module and the parallel control signals are outputted to the steering engine driving control module; and the steering engine driving control module and the steering engine driving module drive a motor to rotate. The general
miniaturization digital electric steering engine controller and the control method thereof disclosed by the invention are high in control speed and stability.
