The invention discloses a steering gear controller. The steering gear controller comprises a main control module, a driving module and a detection module; the main control module is configured to generate a PWM wave signal and an enable signal; the driving module is configured to receive the PWM wave signal and the enable signal, and drive a motor of the external steering gear to rotate; and the detection module is configured to collect a current signal of the external steering gear, collect a speed signal of the motor, collect a position signal of a rocker arm of the external steering gear, and feed back the current signal, the speed signal and the position signal to the main control module; wherein the main control module includes a position control sub-module, a speed closed-loop control sub-module and a current closed-loop control sub-module; and the position control sub-module includes a position closed-loop control circuit and a position feed-forward compensator. The steering gear controller adopts a main control module combining current-speed-position three-closed loop control and position feed-forward control, which can effectively suppress interference, eliminate steady state error, and improve system control precision; and the work is stable and reliable.
Description
technical field [0001] The invention belongs to the technical field of control devices, in particular to a steering gear controller. Background technique [0002] As a key component of the servo system, the steering gear has been widely used in rockets, airplanes, missiles and other aircraft fields. With the development of power electronics technology, these aircraft require control systems with high reliability, high sensitivity, and high precision. [0003] A general steering gear controller is composed of a main control module, a drive module, a brushless DC motor, a detection module and a communication module. When analyzing a brushless DC motor, the existing research adopts a double closed-loop control strategy of speed and position, and through simulation experiments , when a deviation occurs, the controller performs feedback adjustment according to the deviation, thereby eliminating the disturbance, and then improving the stability and response speed of the steering g...
