What is the use of flight control servo?
In the field of drones and aviation models, the flight control servo is a crucial component. It directly affects the stability, controllability and response speed of the aircraft. This article will analyze the function, working principle, application scenarios and popular models of the flight control servo, and combine it with hot topics in the past 10 days to help readers fully understand this key component.
1. The function of flight control servo
The flight control servo is an actuator used in drones or aviation models to control the flight attitude and execute flight control instructions. Its main functions include:
1. Realize the attitude adjustment of the aircraft
2. Respond to instructions from the flight control system
3. Ensure flight stability
4. Improve control accuracy
| Function | Specific role |
|---|---|
| Attitude control | Change the attitude of the aircraft by adjusting the rudder |
| heading control | Control the rudder to achieve steering |
| High degree of control | Adjust the elevator to control climb and descent |
| speed control | Adjust engine power via throttle servo |
2. Working principle of flight control servo
The working principle of the flight control servo can be summarized as follows: receiving the PWM signal from the flight control system, driving the motor to rotate through the internal circuit, and finally driving the rudder surface or control mechanism to produce corresponding actions. The entire workflow is as follows:
1. Signal reception: Receive PWM control signal from flight controller
2. Signal processing: Internal circuitry analyzes the signal and determines the target location
3. Motor drive: drive the motor to rotate to the specified position
4. Position feedback: feedback current position through potentiometer or encoder
5. Closed-loop control: adjust motor rotation based on feedback
| components | Function |
|---|---|
| PWM receiving circuit | Receive and decode control signals |
| Drive motor | Provide steering power |
| reduction gear set | Amplify torque |
| feedback device | Provide location feedback |
| control circuit | Realize closed loop control |
