Abstract:
An electric motor control system includes an electric motor motion signal detection part, configured to provide an electric motor motion signal of the electric motor every other first interval time based on a received first encoder signal sent by the first encoder; a shaft motion signal detection part configured to provide a shaft motion signal of the shaft every other second interval time based on a received second encoder signal sent by the second encoder; and a main control apparatus configured to receive and calculate, according to the electric motor motion signal and the shaft motion signal, an electric motor motion parameter of the electric motor at a moment every other second interval time.

Claim (Index 7):
A control method for controlling driving of a shaft by an electric motor,\n the electric motor being provided with a first encoder with a sampling interval time of a first interval time and the shaft being in transmission connection with the electric motor and including a second encoder provided on the shaft, a sampling interval time of the second encoder being a second interval time, the first time interval being greater than the second interval time, the control method comprising: acquiring a first encoder signal sent by the first encoder to obtain an electric motor motion signal of the electric motor (' 10 ) at each time interval of the first interval time; acquiring a second encoder signal sent by the second encoder to obtain a shaft motion signal of the shaft at each time interval of the second interval time; calculating, according to the obtained electric motor motion signal and the obtained shaft motion signal, an electric motor motion parameter of the electric motor at a time point of each time interval of the second interval time; and controlling the electric motor based on the calculated electric motor motion parameter and an obtained electric motor control signal.
