Low-cost electric steering engine control method based on single-chip microcomputer

Abstract

Provided is a low-cost electric steering engine control method based on a single-chip microcomputer. A steering engine controller is used for controlling a direct-current electric steering engine. An embedded type single-chip microcomputer, a PWM amplifier, a power supply module, a current amplifier and a signal conditioning device are arranged in the steering engine controller. The PWM amplifier and the current amplifier are connected with the direct-current electric steering engine. A position sensor is arranged on one side of the direct-current electric steering engine and is connected with the embedded type single-chip microcomputer. The embedded type single-chip microcomputer acquires signals, coverts the acquired signals into digital signals via programs and using the digital signals as control parameters, and outputs driving signals of the direct-current electric steering engine in a way of PWM waves and phase current to drive the direct-current electric steering engine to move. The position sensor acquires and feeds back the real-time positions of the direct-current electric steering engine to the embedded type single-chip microcomputer, so a position feedback control system is formed for performing high-precision position control on the direct-current electric steering engine. Thus, use cost is effectively reduced, size of the designed controller is small, power consumption is low and the designed controller is high in economical efficiency.

Description

technical field [0001] The invention relates to the technical field of steering gear control, in particular to a low-cost electric steering gear control method based on a single-chip microcomputer. Background technique [0002] DC electric steering gear is widely used in various fields, and it is an indispensable important equipment in automatic control. In order to facilitate the user's use and make the DC electric steering gear work better, it is necessary to configure the steering gear controller to drive the DC electric steering gear. At present, most DC electric steering gears use DSP-based controllers. The controller based on this design can control the position of DC electric steering gears with high precision, but the cost is relatively high, and the volume and power consumption are large. In some The economy is poor in simple applications. Contents of the invention [0003] The technical problem solved by the present invention is to provide a low-cost electric s...
