Embodiment Construction

[0025] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but the embodiments of the present invention are not limited thereto.

[0026] see figure 1 , in this embodiment, the steering gear control system based on fuzzy neural PID control and absolute encoder specifically includes a fuzzy neural PID control unit, an absolute encoder, a serial communication unit, a host computer, and a power module, and the absolute encoder is used for To obtain the rotation angle information of the steering gear, the fuzzy neural PID control unit selects the STM32 control module (STM32FZET6) based on the ARM Cortex-M3 core, and the power module supplies power to the STM32 control module and the steering gear. The output end of the absolute encoder is connected to the input end of the STM32 control module, and the PWM generated by the STM32 control module is output to the steering gear. The maximum operating frequency o...

Abstract

The invention relates to a steering gear control system and method based on fuzzy neural PID control and an absolute encoder. The system comprises a fuzzy neural PID control unit, the absolute encoder, a serial communication unit and a host computer. The host computer and the fuzzy neural PID control unit are connected through the serial communication module. The output end of the absolute encoderis connected with the input end of the fuzzy neural PID control unit. The absolute encoder is used to acquire the steering angle information of a steering gear. The serial communication module is used to receive the control information of the host computer, transmit the control information to the fuzzy neural PID control unit, and send the position information of the absolute encoder to the hostcomputer. The fuzzy neural PID control unit receives the control information of the host computer, drives the absolute encoder to rotate, calculates steering gear control parameters to generate a PWMsignal, and outputs the PWM signal to the steering gear. The steering gear control system and method based on fuzzy neural PID control and the absolute encoder have high control precision, and solve the problem that the existing steering gear control technology has poor adaptability and robustness and is not flexible to the joint motion of a robot.

Description

technical field [0001] The invention belongs to the technical field of steering gear control, and in particular relates to a steering gear control system and method based on fuzzy neural PID control and an absolute encoder. Background technique [0002] In recent years, with the continuous development of fields such as robotics and artificial intelligence, the use of steering gear has become more and more frequent. The steering gear is an important control component. The standard steering gear generally has three wires, which are GND, VCC and control wires. The steering gear is mainly composed of the following parts: rudder plate, reduction gear set, position feedback potentiometer, DC motor, control circuit board, etc., in which the DC motor passes through a series of gear sets, and the rudder plate as the output and as the control The feedback potentiometer is connected. There is a reference circuit inside the steering gear, which generates a reference signal with a peri...
