The invention relates to the technical field of
spacecraft control and particularly discloses an integrated analyzing and setting method for
control parameters of a three-loop automatic
pilot. The integrated analyzing and setting method comprises the following steps of: firstly, establishing a control loop model of the three-loop automatic
pilot; secondly, setting a pitching motion relative damping coefficient after compensating an attitude
angular velocity feedback circuit to acquire an attitude
angular velocity control parameter and the open-loop cross-over frequency of the attitude
angular velocity feedback circuit; thirdly, acquiring an open-
loop gain system of a
control system according to an open-loop
transmission function of the
control system and acquiring a closed-loop
transmission function which is inputted to a guidance
spacecraft by an overload instruction after correction and is outputted in an overload manner; and fourthly, acquiring the attitude angular velocity control parameter, an overload
feedback control parameter and an overload instruction correction parameter. According to the integrated analyzing and setting method, the solving of a nonlinear equation is avoided; in addition,
attitude stability and
attitude control precision of the guidance
spacecraft can be maintained by the acquired parameter under various single deviations and combined deviation and the balancing state of the spacecraft required by the guidance instruction is quickly realized.
