Abstract

The invention belongs to the technical field of electric servo control, and discloses a double-shaft steering engine controller based on an MCU processor. The controller comprises an MCU processor, anoperational amplifier, a bus transceiver and two motor drivers. The operational amplifier, the bus transceiver and the motor driver are all connected with the MCU processor, and the operational amplifier is further connected with two position sensors arranged on the steering engine. The operational amplifier is used for receiving two paths of steering engine position feedback voltage signals sentby the two position sensors, amplifying the signals and sending the signals to the MCU processor. The MCU processor generates two paths of modulation pulse width PWM signals according to the steeringengine position instruction signals and the two paths of steering engine position feedback voltage signals received by the bus transceiver, and respectively sends the two paths of PWM signals to twomotor drivers to carry out power amplification on the PWM signals to obtain motor driving signals, and outputs the motor driving signals. The high-integration MCU processor and the H-bridge motor driver are adopted, so that the circuit design is simplified, the engineering implementation is simple, the size is small, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of electric servo control, and relates to a dual-axis steering gear controller based on an MCU processor. Background technique [0002] The steering gear is a position (angle) servo drive, suitable for those control systems that require constant changes in angle and can be maintained. It has been widely used in high-end remote control toys, such as airplanes, submarine models, and remote control robots. [0003] Existing servo controllers are generally composed of processors and their peripheral circuits, signal conditioning circuits, AD conversion circuits, half-bridge drive circuits, H-bridge inverter circuits, power circuits, and bus transceivers. It is not high enough, and it is necessary to increase the peripheral clock, reset and watchdog circuits. The accuracy of the AD converter inside some processors is poor, and an external AD converter needs to be added. At the same time, the motor drive circuit ...
