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 10):
The control method of  claim 9 , wherein the calculating of the electric motor motion parameter at the angular position change time\n further comprises: obtaining, according to the electric motor motion signal acquired at an angular position change time T, an angular displacement \u03b8 m  of the electric motor and a rotational speed \u03c9 m  of the electric motor at the angular position change time T, and obtaining, according to the shaft motion signal acquired at the angular position change time T, an angular displacement \u03b8 L  of the shaft at the angular position change time-T, and controlling rotation of the electric motor according to the rotational speed \u03c9 m  of the electric motor and the electric motor control signal at the angular position change time T; wherein the obtaining of the angular displacement of at least one of the electric motor and the shaft further comprises calculating an angular acceleration of the electric motor at the angular position change time T according to the angular displacement \u03b8 m  of the electric motor and the angular displacement of the shaft at the angular position change time; and wherein the calculating, according to the electric motor motion parameter at the angular position change time T, the electric motor motion parameter at each time interval of the second interval time \u0394t, until the first encoder detects the next angular position change time T\u2032, further comprises: obtaining an angular displacement \u03b8 L+1  of the shaft at a time T + \u0394t according to the shaft motion signal acquired at the time T+\u0394t, calculating a rotational speed \u03c9 m+1  of the electric motor, an angular displacement \u03b8 m+1  of the electric motor, and an angular acceleration \u03c9 ma+1  of the electric motor at the time T+\u0394t according to the rotational speed \u03c9 m  of the electric motor and the angular acceleration \u03b1 m  of the electric motor at the angular position change time T, and the angular displacement \u03b8 L+1  of the shaft at the time T + \u0394t, and controlling the rotation of the electric motor according to the rotational speed \u03c9 m+1  of the electric motor and the electric motor control signal at the time T + \u0394t; and making T=T+\u0394t, and upon at this time T+\u0394t being less than the next angular position change time T\u2032 of the first encoder, then \u03b8 m =\u03b8 m+1 , \u03c9 m =\u03c9 m+1 , \u03b1 m =\u03b1 m+1 , and returning to the obtaining of the angular displacement \u03b8 L+1 ; and upon at this time T+\u0394t being equal to the next angular position change time T\u2032 of the first encoder, then T=T\u2032, and returning to calculating of the electric motor motion parameter at the angular position change time.
