What is the PID of CC3D?
In the world of drones and model aircraft, CC3D (OpenPilot's Control Board) is a widely used flight control system. PID (proportional-integral-derivative) control is one of the core algorithms of CC3D flight control, which is used to stabilize the attitude and movement of the aircraft. This article will introduce in detail the PID control principle of CC3D, the parameter setting method, and the hot topics and hot content in the past 10 days.
1. PID control principle of CC3D
PID control is a classic feedback control algorithm that achieves precise control of the system by adjusting three parameters: proportion (P), integral (I) and differential (D). In CC3D flight control, PID control is mainly used in the following aspects:
1.Attitude control: Ensure the stability of the aircraft on the roll, pitch and yaw axes by adjusting the PID parameters.
2.High degree of control: In altitude hold mode, PID control is used to maintain the target altitude of the aircraft.
3.position control: In GPS mode, PID control is used to maintain the precise position of the aircraft.
2. PID parameter setting of CC3D
The PID parameter setting of CC3D is usually completed through the OpenPilot ground station software. The following are common adjustment ranges and recommended values for PID parameters:
| parameters | function | Recommended value range |
|---|---|---|
| P (proportion) | Response speed | 0.1-2.0 |
| I (points) | Eliminate steady state errors | 0.01-0.5 |
| D(differential) | suppress oscillation | 0.0 - 0.2 |

4. Practical skills for PID parameter adjustment
1.Gradual adjustment: Adjust only one parameter at a time and observe the aircraft's reaction to avoid confusion caused by adjusting multiple parameters at the same time.
2.logging: Use ground station software to record flight data to facilitate analysis of the effect of PID parameters.
3.Reference community experience: Many aircraft enthusiasts will share their PID parameters on the forum, which can be used as a reference.
5. Summary
CC3D's PID control is the key to the stable flight of the aircraft. By properly adjusting the PID parameters, the performance and stability of the aircraft can be significantly improved. Hot topics in the past 10 days show that PID parameter adjustment skills and firmware updates are the focus of the community. I hope this article can help you better understand the PID control of CC3D and achieve better results in actual flight.
