High Accuracy and High Collaboration Control Algorithms
SIYI has made multiple breakthroughs in control algorithms and stabilization
algorithms.
IMU Calibration Algorithms
Compensate and correct errors of the inertial measurement unit, reduce
interference factors such as zero bias, scale factor, inter-axis error, temperature
drift, noise, etc., greatly improve the measurement accuracy of IMU, and improve
the stability of the gimbal in large temperature differences, wide margin steering,
and strong vibration environments.
Attitude Fusion Algorithms
Comprehensively utilize the data of sensors such as accelerometers and
gyroscopes, obtain the pitch angle, roll angle, and yaw angle of the gimbal through
mathematical models and filtering algorithms, and fuse this information to effectively
improve system performance, stability, and robustness.
Industry-Level 3-Axis Stabilization Algorithms
Deeply integrate and utilize 3-axis gyroscopes, 3-axis accelerometers, PID
controllers, motors, and magnetic encoders to achieve gimbal attitude stabilization
control and continuously output stable high-definition video images during motion.
High-Precision FOC Motor Control Algorithms
Control the current components of the motor to control torque and magnetic field
respectively, thereby achieving decoupling control of the brushless motor and
greatly reducing picture jitter.
