Abstract
The invention belongs to the technical field of motor servo control, and discloses an embedded type motor modularization servo controller of a flight simulation rotary table to solve the problems that the driving cost of an existing single-shaft flight simulation rotary table is high and the servo function of an upper computer is limited by a large working load. According to the embedded type motor modularization servo controller, a main controller is formed by an ARM and an FPGA and receives a control command of an upper computer, and sends the control command to a shaft controller after simple calculating. The shaft controller is formed by a DSP and an FPGA and receives the command sent by the main controller, the DSP carries out control command calculation, and the FPGA carries out logical operation and sends a signal to a driver to drive a motor to finish the appointed task. An EtherCAT industrial bus is adopted in communication between the main controller and the shaft controller. The upper computer IPC is mainly used for carrying out human-computer interaction and a little data size calculation, and sending data information to the main controller through the network. The embedded type motor modularization servo controller is used for controlling the motor of the flight simulation rotary table.
Description
technical field [0001] The invention relates to an embedded motor modular servo controller of a flight simulation turntable, belonging to the technical field of motor servo control. Background technique [0002] The flight simulation turntable is a high-precision complex control system, which is used to simulate various actions and attitudes of the aircraft in the air. High-precision sensors such as gyroscopes and seekers are installed on the turntable to control the various attitudes of the aircraft in the air. The electrical signal is converted into the mechanical rotation of the turntable to move the attitude angle of sensitive aircraft such as gyroscopes and seekers. "High response, ultra-low speed, wide speed regulation, high precision" has become the main performance index and development direction of the simulation turntable. Among them, "high frequency response" reflects the strong ability of the turntable to track high-frequency signals; "ultra-low speed" reflects ...
