Non-steady-state-error-constant-speed-based position servo system control method

The invention provides a non-steady-state-error-constant-speed-based position servo system control method. A controlled object gain of a position loop is calculated according to a speed ring gain, a speed ring time constant, a total transmission ratio of a motor to an execution mechanism end, and a position feedback coefficient of a servo system; a natural frequency, a position controller integral gain, a proportional gain, and a position error are calculated successively; and then an output of the position controller is obtained finally. According to the invention, with the method, the system has advantages of fast response speed and stable transient process during the step response or ramp response process, so that the control performance of the position servo system can be improved.
