Description

Technical field [0001] The invention relates to an electric steering gear control system, in particular to an electric steering gear control system based on DSP and CPLD, and belongs to the field of electric steering gear automatic control. Background technique [0002] The electric steering gear is the actuator of the flight control system of missiles, unmanned aerial vehicles and other aircraft. The various movement attitudes of the aircraft in the flight process are realized by the steering surface deflection driven by the electric steering gear, and its performance directly affects The performance of the aircraft. Brushless DC motor, reducer, controller, drive circuit and various sensors constitute the hardware part of the electric steering gear control system. The control algorithm uses three closed-loop PI controllers, which form a complete electric steering gear control variable structure PID control It is a commonly used electric steering gear control method. The variab...
