The invention discloses an
intelligent control method and
system for a
clock micromotor, and relates to the technical field of
intelligent control, and the method comprises the steps: obtaining the environment temperature, the gravity angle value and the standing time of the
clock micromotor, taking the environment temperature, the gravity angle value and the standing time as orthogonal variables, constructing a multi-dimensional friction load tree, and according to the multi-dimensional friction load tree, carrying out the
intelligent control of the
clock micromotor. The method comprises the following steps: obtaining a reference driving pulse width, calculating a
time difference value between an actual back
electromotive force zero-crossing moment and a theoretical back
electromotive force zero-crossing moment, outputting the
time difference value as a load residual error, storing the load residual error according to a
time sequence to form a historical load residual error sequence, and obtaining a trend correction factor according to the historical load residual error sequence; compensating the reference driving pulse width through the trend correction factor, generating a target driving pulse width, outputting a driving waveform to a coil of a clock micromotor according to the target driving pulse width, controlling the operation of a rotor, updating a historical load residual error sequence according to a real-time load residual error, and improving the
travel time precision, battery endurance and mechanical life of the clock.
