The invention provides an
inertia rate composite stable
control system, wherein a
servo controller is electrically connected with a
servo turntable, the bottom seat of the
servo turntable is connected on a base platform, a turning direction of the servo turntable is parallel to a sensing shaft of a first angle rate
gyroscope and a sensing shaft of a second angel rate
gyroscope; the first angle rate
gyroscope is arranged on the base platform, and is used for generating a disturbing
signal of the base platform and outputting a feedforward stable
control signal; a
speed measurement machine is connected with a rotating shaft of a motor through a connecting shaft; the
speed measurement machine is used for obtaining a motor rotating angular speed
signal; the second angle rate gyroscope is arranged on load and is used for obtaining an angular rate
signal of the servo turntable to achieve a feedback stable loop; the servo controller receives and utilizes a speed given signal, a top feedback signal, a top angular rate feedforward signal and a
speed measurement signal of the speed measurement
machine to achieve a speed control loop, the feedback stable loop, feedforward stable control, to generate a speed output
control signal, to output the speed output
control signal to the motor, and to achieve closed-
loop control.
