Abstract

The invention discloses a control system and control method of a steering engine. The steering engine comprises a DC motor and a control system thereof. The control system includes a main control chip, a power supply circuit, a motor driving circuit, a position acquisition circuit and a host computer. The power supply circuit supplies power to the main control chip, the motor driving circuit and the position acquisition circuit. The main control chip is connected to the motor driving circuit and the position acquisition circuit. The position acquisition circuit is used for collecting a position of the steering engine and sending the signal to the main control chip. The host computer is in communication connection with the main control chip to send an operation instruction to the main control chip. The main control chip is used for calculating and outputting a PWM wave according to the position information of the steering engine and the operation instruction and sending the PWM wave to the motor driving circuit. The motor driving circuit is connected to the DC motor to control the DC motor according to the PWM wave to further control the movement of the steering engine. According to the control system and control method of a steering engine, a problem of a complex control mode is solved.

Description

technical field [0001] The invention relates to the field of steering gear control, in particular to a steering gear control system and a control method. Background technique [0002] As a servo actuator, the steering gear is widely used in aircraft, missiles, rockets and other aircraft. Since these modern aircraft require the control system to have high precision, high sensitivity and high reliability, higher requirements are placed on the performance of the steering gear. , to promote the development of steering gears in the direction of continuous reduction in quality and volume, continuous increase in carrying capacity, and continuous improvement in control performance. Therefore, the research and development of new high-performance steering gears has attracted great attention from military and scientific research institutions in various countries. [0003] The steering gear can literally be understood as the motor that controls the rudder surface. Generally speaking, t...
