The invention relates to an FC-AE-1553 optical fiber bus communication servo controller, which includes a signal processing unit, a digital signal processing unit, a field programmable gate array unit, a 1553 protocol processing unit, a secondary power conversion unit, and an optical network unit photoelectric converter unit. Compared with original MIL-STD-1553B bus servo controllers, the servo controller has the original servo controller scheme functions of motor current, rotating speed, actuator displacement acquisition, signal processing, closed-loop operation control and servo state information feeding back to a control system, meanwhile, the servo controller can be externally connected to an optical fiber bus to realized fiber optic communication based on an FC-AE-1553 protocol, the bus communication rate is increased 2000 times to 2 Gbps from 1 Mbps of an MIL-STD-1553B protocol, and the communication bandwidth is greatly increased; and meanwhile, bus communication transmission ischanged to optical signals from electrical signals, anti-electromagnetic interference performance of bus communication is improved, and the weight of a bus transmission cable is decreased.
Description
Technical field [0001] The invention relates to the field of servo control and communication, in particular to a servo controller. Background technique [0002] The servo controller can be used in the rocket electromechanical servo system. The role of the servo controller in the rocket electromechanical servo system is to control the servo driver to drive the actuator according to the servo command issued by the control system to complete the attitude adjustment of the rocket nozzle, and at the same time feedback the servo status information to the control system for the control system The normal servo running status is monitored and evaluated. The existing servo controller bus communication generally uses the MIL-STD-1553B protocol, which has the following disadvantages: [0003] 1. The communication rate is 1M bps. The servo system can only feed back limited servo status information to the control system in each servo closed loop cycle, which makes the control system evaluate t...
