Abstract

The invention relates to an electric steering gear step response peak current suppression method and system, and belongs to the field of the motor control. The problem that the steering gear outputs large current peak when the existing electric steering gear is in great step response is solved. The method comprises the following steps: judging an instruction signal input into a controller, and identifying a step signal; performing response control amount shaping on the output step response; judging the shaped step response to identify the porting stage of the step response; performing portingcontrol amount shaping on the step response at the porting stage; sending the shaped control amount to the electric steering gear to control the work of the electric steering gear. By dynamically adjusting the control amount, the motor armature peak current is weakened, and the effective output duration of the armature current is increased; and the dynamic feature of the electric steering gear isguaranteed while suppressing the armature current peak. Additional hardware resource expenditure is avoided, the volume and the weight of the electric steering gear control system cannot be increased,and the reliability and the electromagnetic compatibility of the electric steering gear can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of motor control, in particular to a method and system for suppressing a step response peak current of an electric steering gear. Background technique [0002] The electric steering gear servo system is a high-precision position servo system, which is mainly used in aircraft, ships, submarines, robots and other fields. The task of the electric steering gear is to precisely control the deflection of the rudder surface, so that the controlled object can reach the expected attitude or position. The high dynamic and fast response capability of the electric steering gear determines the dynamic quality of the attitude control system of the whole machine on the platform. [0003] Taking the electric steering gear for missiles as an example, the flight conditions of the missile are extremely complicated. When the missile is disturbed by severe airflow or maneuvers quickly in a wide range, the steering gear needs to...
